I have maybe a very different perspective from a lot of folks here on this one, as I am childfree (borderline antinatalist) and really don't like being around kids, at all.
Given the above, I am quite biased but I find the attitudes listed in the OP to not necessarily be true, if anything I find it increasingly the opposite. Fewer places are actually childfree these days. I totally understand that if I go to a public park there will be children, I have no qualms with that, but maybe the whole family doesn't need to head out to the local brewery.
Going to school has been the worst thing I’ve ever had to endure.
This one I am mixed on. Middle school and high school were awful, at least socially, but I also had magnitudes more free time back then than now. Getting home by 3 or 4 PM as opposed to 9 or 10. I could, and frequently did, spend all day reading. University, on the other hand, while stressful was probably one of the best periods of my life.
