So any definition of a word that is illogical is that way because of agendas and propaganda?
No. That's merely the reason the commonly accepted definition of "homosexual" is as it is.
If someone puts a gun to your head and forces you to have sex with another man you choose to have sex with a man.
Obviously if someone is forcing your choice of partners then it has no bearing on your choice of sexuality.
There are lots of men in prison choosing to have sex with men. When they leave they usually do not become gay.
So they were gay while they were in prison and decided not to continue having sexual relations with men when they leave. Obviously that is a choice they can make. If they only have sex with women from then on, they have chosen to become heterosexual again.
This is a case in point of my saying that sexuality is a choice.
I want to be with women. I like looking at them. I fantasize about them. If a woman bends over I check out her cleavage. I do not have any interst in men in this way.
So you choose to look at women and men differently. There's no reason you couldn't look at men the same way as women if you wanted to, but you choose not to. Great for you.
