That would be fine if the joke was actually accurate. Let’s go through it point by point, shall we?
~Does not reproduce
Bold lie. Where do I even begin to explain? Lesbians that go to a sperm bank can reproduce. Trans before medical transition can, multisexual ppl can, all of ace-spec can, and so on.
~Only 6 colors
If they only mean the pride flag shown, then sure. There’s variations on the pride flag with multiple colors through. This one’s not really a big deal through
~Biased and selective about what is “offensive”
This is somewhat true, although normally something like this comes up when someone who isn’t queer doesn’t know how to make a joke about queer people. They try to be lighthearted and what not but end up just being discriminatory. This one is kind of a mixed bag
~Can’t handle jokes
Similar point to the previous one. This is somewhat true. Some can and some can’t. It’s a mixed bag tbh
