"I see it more as a fad/hype really."
Because you don't want to believe that rational people could choose differently than you. I bet you think godlessness is a fad/hype as well?
"Kids see it's popular"
You don't know any kids. I'm 18, I know 2 gay guys. One killed himself last week, the other was thrown out of his house and lives on youth allowance and govt housing assistance.
Gay/fag is a very common insult, so much so it has basically created a 3rd meaning of the word totally separate from the previous meanings. Homosexuality is not, by any stretch of the imagination, popular.
"so they do it and most remain that way because they seem to like it."
Even a Cosmo study found that straight guys don't get turned on by gay porn! Any credible study will show this! Homosexuality does not happen like that!
"50 years ago the homosexual population was not even 1% of the total population in the U.S"
[citation needed]
"all of a sudden it's between 10-20%"
you mean since people started coming out after the 60's? 40 years is not "all of a sudden", have you been living in a closet all this time?
"nowadays most cartoons for kids even show homosexual behaviors."
Alot of cartoons include some kind of M/F love interest or dynamic. Spongebob is the only cartoon I know with such homosexual undertones and you'll only see them if you're looking for them.
"Perhaps TV is what's causing this"
So many people have said that about so many modern issues.
