kinda scared to ask since it's a hot topic

"Don't ship them cuz they're underage"....my internet friends preach this but they shipped younger Hinata with younger Kiba, watch highschool romance. Are they hypocrites? they only preach this line thou when they stumble on BL/GL ships. The posts are completely cute btw not the SPG kind of thing. Are they correct? Hypocrites? Homophobic?
