How many genders are there ?

There are only two genders, period. No other things. I've seen people mention trans and non binaries, and there's simple solutions to that. Trans or not, you're still one of the two in the end. Non binary? Bro just look beneath your pants and find out which gender you are. And then there's like a bajilion of other made up bullshit but we can all agree that it's just plain retarded.
