Using the word "homophobia" in regard to a legal choice to beleive one's religion is HATE speech no different than using the N word.

Referring to religion as mythology is also HATE speech.

You appear to only recognize free speech as speech that agrees with you. If you don't want to send money to scouting, that is your choice. If you don't want to have anything to do with them, fine. If you want to try to persuade them that they are wrong, with logic not violence, fine.
