I firmly believe that jfm would be 'he's confused but he's got the spirit' brand of supportive to wwx being into men. like obviously putting wwx on a pedestal/projecting onto him/viewing him as an extension of his parents and therefore a vicarious way for jfm to experience freedom and adventure again isn't good for him, but it does mean that he doesn't really interfere with how wwx behaves or wants to be bc he wants him to be free. I really do think his fondness for wwx would supercede any homophobia he harbors from like, his upbringing. he's a terrible father and very misguided and all but he really does love wwx and any reading of him that paints him as loudly homophobic while myu of all people is the supportive one just reads as extremely stupid to me. jfm obviously favors the son that's not his and that wouldn't stop just bc that son is gay
