Being gay is fine.
Organizing gay events to talk and share their stories is fine.
Organizing marches to demand for equal rights is fine.
Going out in public with your significant other, holding hands, kissing is fine too.
Stating what is a decent behavior outside is kinda relative. For an islamist for example, even a straight couple holding hands and kissing on the cheeks is indecent. You can't make a law that forbids what YOU find offensive. People get offended by too many things, that are different of what is considered offensive by some other groups.
I ,for example, get offended by Mosques and Churches, and find them as places where people celebrate having no clue whatsoever, but you don't see me arguing for banning Mosques and Churches .
Muslims get offended by people drinking, how would you feel if they wanted to make a law that states anyone who wants to drink can only drink in his home?
I do understand @Dark Angel 's points in here, and I do believe he is VERY FAR from being a homophobic and he is just concerned about public decency (unlike @JustLeb who have experienced some very nice DVDs that shaped his views XD).
But how can you come to an objective view of what is a decent behavior in public? for me as long as people aren't running naked in the streets it is fine.
this is where we disagree. i personally i am not offended with public displays of affection within a certain limit, as i have pointed out, a quick peck is not a big deal whereas people having their tongues in each others throats is something they should have the respect and the decency to do in private. decency is an axiom of the social contract that should be adhered to. there is a time and a place for everything, and these are usually givens and they fall under the common sense perspective. personal freedom does not allow for violating the norms of public decency.
the islamic tradition however is a different story all together, the perspective of personal freedom is not pretty much non existent, and many of the basic individual rights are not even recognized, consequently freedom of thought, freedom of expression and freedom of worship take a major hit under the islamic banner. and that is reflected in many aspects through a mix of tradition and sharia laws. we just began ramadn for instance, and most islamic countries and cities outlaw eating in public during the fast hours, the same goes for drinking. whereas in Christianity where free will is a major component of the faith you cannot really note whether people are fasting or not. and that is without even visiting the part where gay people are automatically put to death according to the islamic sharia laws.
in short, you have to have a valid rational reason to be offended, it is not a matter of whims. if you however still feel offended at the sight of a church then an exorcism might be in order
