It makes them feel more secure about their own sexuality.
I think in most cases, they don't realize how hurtful they're being. If it were pointed out to them, they'd understand.
Some gay people are funny and some are not. Being gay has nothing to do with being funny.
In my experience, gay people laugh at pretty much the same things as heterosexual people.
I've heard that no, it's a joke and during an awkward silence you can just say "GAY BABY" and it makes people laugh.

Being gay is not an idea. It is a part of a person's identity. Its part of who they are. Gay people have been around since people have existed and will continue to do so well into the future. Their is no choice in being gay. Some people might disagree with this but the biological evidence is overwhelming that being gay is genetic and the environment may have some influence.
Being gay is not a decision. It's something you are either born with, you are not. But yes, some people are embarrassed about being gay.
How can you not laugh.
Being stuck up is a personality trait, usually born from vanity and narcissism, and has no direct correlation with being gay. Yes some gay people can be stuck up, just as some straight people can be stuck up, but there is nothing that ties being gay with being stuck up.
Sometimes being gay is difficult on a person because of the majority of society's view on homosexuality. Some gay people may try to hide their sexuality or try to become "not gay" but because being gay is biological and not a choice, there is no way to "get out" of it.
You say it like "gays" are some other species. They are just as equal as we are. Being gay is just as simple as having different opinions on Politics. Therefore, some people will like cheese. Some won't. Being gay has nothing to do with it.
they say that to make people laugh
