Do not use the word “gay” to describe homosexuality. That word was invented for the purpose by queers who use it to hide the reality. There is a catalog of pejoratives you can use, or the more clinical (but perfectly accurate) “homosexual.” But avoid the use of the lie that is “gay.”
EXACTLY. Stolen concept.
I would also avoid the use of the term “homosexual.” This purposely confuses those who merely have a same-sex attraction with those who engage in buggery (I like that term). The former deserve our sympathy and support while the latter deserve our condemnation. This distinction should also be applied to all calls to avoid discrimination; for the former yes, for the latter no.
