Showing gay characters is one thing, but glorifying the openly gay lifestyle is another, especially when they convey casual sex encounters as common. If this is shown enough on TV shows, commercials, movies, the more people will become used to the idea and eventually it wont be taboo at all...this 'tactic' can also be used for agendas, not just LGBT lifestyles, at some point, it will probably be used in attempt to 'normalize' pedophilia' to some degree, it really is already happening, Ive seen quite a few shows/ movies that depict a middle aged man having a sexual encounter (or desiring such a thing), with a 16-17 yr old female, this isnt really pedophilia, but it 'breaks the ice' and paves the way later on for acceptable 'trysts' with younger people. A common theme is "whats age got to do with anything, we are just out to have a good time".

I think Hollywood tries to convey what they think a 'normal' lifestyle should be, it is accomplished by showing character reactions to such things, their emotions, etc, they know how to spin it, so people come to think its all normal, in the 90s, they tried the same thing, but in attempts to depict strong single women, in otherwise normally male jobs, like cops, detectives, judges, etc, but if you looked at real life, there were not many females like this out there...its just something Hollywood (or someone above them) wanted to become normal
