A lot of stadiums have VIP lounges and the like. Not sure how else to explain this. But yes, smaller stadiums are less likely to have them.
Because the more space you have between seats the less people you can fit into a certain area. Why do you think business class flights are more expensive than economy? Additionally, in a sports stadium, the more space there is between people, the less of an atmosphere you will have.
No, that part was simply to point out that some families seem to manage to go to stadiums without issues. I cannot say "I take my kids to football games" because I don't have any. My experience was as the child. Not as the parent. No history be known.
What others have you gone to? Because that was my other point. Most sports venues I have been to, are not family friendly, at least not in the sense that you describe. This isn't unique to football. In fact, ice hockey was even worse. And to a certain degree this should be obvious. You are there to enjoy the game. Not walk around constantly and not to enjoy vast amount of space.
I never once said "women don't support the game". Not sure where that is coming from.
Basically your post reads like something on r/FuckYouKaren (reddit sub where people make fun of real life examples of 'Karens') sounding like "football stadiums need to be rebuilt because I can't buy seats at the end of a row to easily get to the toilets or have my children sit still for 45 minutes and I feel like a sardine".
