I will assume you are legitimately asking in good faith as this is a fairly common bingo we hear a lot.

Someone's age and the way they act is not the same as their sexuality. That should go without saying, but you would be surprised.

People tend to find children annoying because of...the behaviour of children, unsurprisingly. Whether that is the crying, the demand for attention, the manipulation, the risk of damage (to themselves, me or my possessions, or others). Those are regardless of race, gender, sexuality, etc.

Doesn't mean I actively wish ill on them; quite the contrary, I respect them as much as I would the life and livelihood of any other human. I just made the choice to have nothing to do with them. My partner is the same, so it's never been a particularly big issue for us. We just don't go to places where there are likely to be kids, and everyone is happy. Do I expect that in some public places there will probably be children sometimes? If it's an appropriate venue, yeah I just have to deal with it.
