Whether you are a fan of those characterizations or not. It's real.
There is a publicly recognized stereotype of gay man (essentially Jack from Will & Grace) which is not a faithful depiction of many homosexual men, I find wrong to assume that it is indeed faithful (all gay man are like that and vice versa). What I think will be a solution to this prejudice is not negating the stereotype but divorcing it from the actual sexual orientation of the individual.
I believe that many heterosexual males would be more comfortable with a more effeminate personality and that an homosexual can be at any point of the "virility" spectrum, still the spectrum exist.
I am not who you are answering to. I don't think purple-dragon is being irrational here, you initial comments were easy to misunderstand and negative stereotypes of homosexuality are still a problem today. Assuming goodwill I actually think that your comment had nothing wrong in it (assuming you do not actually think that that flight attendant "must" be gay or that all gay behave like that), still purple-dragon is not wrong either in reading it as a negative depiction. Internet conversations are just hard...
