homophobic boy doesn't understand satire

bㅂ🏳️‍🌈✨
went to Toronto pride this year and absolutely loved this sign I saw in the Catholic Pride float. Obviously it's comical and satirical and shows not all religious people are filled with hate towards the LGBT+ community. 
This guy I know who claims he's not homophobic but always starts fights with me on LGBT related issues starts going off in the comments. What are your thoughts on this lol?
