"how can m/f ships be good-" first of all through the power of bisexuality anything is possible so write that down. second of all if we start othering ships based on gender and nothing else we're no better than the opposition. third of all you need to watch more addams family
If your primary concern in a ship is "they're two guys!" or "they're two girls!" or "one of them is nonbinary!" then it's going to be every bit as soulless as "Guy and Girl in close proximity, of course Romance will happen". If your judgement of whether a relationship is good is based on the genders of the participants then I don't trust you to write good romance.
