To answer your question directly, please consider the following:
1) Sectarian political discourse: Bassil's consistently sectarian political discourse: the "christian rights" mantra.
This discourse is not only ethically wrong, and damages our national fabric...it is also a lie.
Ethically wrong: You are the head of a party that calls itself the"Free PATRIOTIC Movement" , which also calls for secularism. People expect you to adopt a discourse that is in line with these principles: advocating for the rights of all Lebanese, from north to south. When they hear you boldly and rudely emphasise on the rights of only one sect, all the time, they will directly question the credibility, honesty and intentions...not only of you, but of your party as well. As Bassil has managed to maintain this divisive sectarian discourse over the years...I can assure you that he and his party have lost credibility and trust by a vast section of the Lebanese public + it generated hate and repulsive attitudes towards that party and its leaders, especially him.
It is a lie: If Bassil truly is advocating for Christian rights, one would argue that well, he is doing what every other party is doing: advocating for the rights of its own sect. But he isn't. He's actually advocating for the rights of his close inner circle, and those who support him...in other words, its not '72oo2 el masi7iyeen',...rather it is '72oo2 el ma7sobeen 3leh' ... and there's a big difference between the two. If it was Christian rights that he was worried about, he wouldn't have fought the Lebanese Forces and the Marada party over their share in every level of decision making...government, appointments, and much more. They are predominantly Christian parties too, and Bassil has a hobby of consistently fighting them.
Result: Bassil discredited, hated. FPM's image: damaged
2) Failing to deliver on promises + blaming everyone else: His party has been handling the electricity ministry for most of the past 10 years, and his political group has the majority of the current government AND the parliament AND the presidency. Yet, he never assumes responsibility, and whenever someone questions the lack of achievement and the corruption, he blames others. Sorry, but people are not stupid to buy that.
Result: Bassil discredited, hated. FPM's image: damaged
3) FPM Presidency: The way he has presided over FPM: He won with no competition - not by coincidence, but by clear and repeated internal efforts to prevent anyone from challenging him. This is not a secret. More so, it is a traditional behaviour of dictators and those who have a lust for power. FPMers and non FPMers watch this, and understand the meaning behind it: Me or no one else. And let me quote what President GMA once said: "Ne7na ma 3enna nowweb bl tazkiyeh!" .. yeah right.
Result: Bassil discredited, hated. FPM's image: damaged
4) Sectarianism, again: Bassil's consistent unconstitutional refusal to approve the rightful employment of public employees. His justification is that there is no "sectarian balance" in the background of those who qualified. The constitution clearly says that sectarian balance is applied ONLY in first level positions. Using his fake "Christian rights" mantra, and driven by his deeply sectarian mentality, he continues to refuse to allow this bill to pass, and managed to convince his father in law too. Result: Hard working, well deserving public employment test winners have been denied a job they not only deserve, but desperately need. More so, when faced with a question on this issue, he rudely said: "whoever doesn't like this, will have to get used to it" (or something similar).
Rude, arrogance, sectarian and denying people's right to be employed. Wonderful
Result: Bassil discredited, hated. FPM's image: damaged
5) Fake alliances: People have come to realise that Bassil's alliance with Hezbollah is for pure personal and narrow political purposes. One evidence: When he famously said Israel has the right to "live in peace" and that Lebanon does not have an "ideological struggle" with Israel. Two heavy statements that contradict with Lebanon's core struggle with Israel. Another evidence, when he said "2aleeleh shu 3emlo fina el Hezeb?" speaking about the previous elections. His alliance is simply to accumulate more power and support - not because he genuinely believes in anything that Hezbollah stands for or sacrifices. Let's not forget that Bassil was the 'engineer' of ending the alliance with Marada and backstabbing the Lebanese Forces after the agreement with them. So much for Christian unity eh?
Result: Bassil discredited, hated. FPM's image: damaged
6) No accountability, no responsibility: Despite all of the above wrongdoings, Bassil never acknowledges responsibility, changes course, or even apologies. Acting like a flawless saint. People see this. Again, we're not stupid. We see this, and it makes us even more eager to blame him and accuse him
Note that in all of the above, Bassil's 'Baltajeh' comments on Berri wasn't an issue. We all know politicians hate each other but are forced to deal with each other. And that's a Bassil-Berri problem. Not a Bassil-Lebanon problem. The issues above are Bassil's issues that harmed Lebanon and FPM.
We all know he works hard. We don't care how hard he works, we care HOW he works. On what principles. On what basis. For what purpose. So far, he's been shooting FPM and the Presidency in the heart.
Result: "Hela Hela....Hela Hela Ho .... " being chanted across Lebanon, every single day ....the FPM facing a major image problem....and the Presidency's achievements are in grave danger
What's worse? FPM party members continue to blindly support and follow Bassil. How wonderful and comforting!!
