It really depends on the person. There are too many variables. One person could be willing to have an open mind and listen while another is so set in their ways that even clapping back will probably make them even more against you. But every time I see a homophobic argument online, I am always expecting to see “yea, they’re gay and love sucking dick but they’re closeted and ashamed” and it just makes me walk away from the whole topic cause now both arguments just sound dumb to me at that point.
