This is funny and I agree with the message, but the logic doesn’t work. If you apply it to anything other than gay marriage, it’s clear why: homophobes oppose gay marriage on (allegedly) moral grounds; telling someone to simply not engage in (what they see as) immoral behaviour rather than opposing those who perform said behaviour falls apart if you substitute anything generally regarded as immoral, such as stealing or murder. “If you don’t like it, don’t do it,” is fun to say to fellow allies, but a genuine homophobe can just reply, “well if you don’t like assault, don’t assault someone” as they attack you. I think a better argument would note the fact that any marriage only concerns those getting married, and doesn’t harm anyone. “If you oppose gay marriage, mind your own damn business”.
