Why is that so uncomfortable? Kids are like pets, if you have them then you are more tolerant of others, but if you don't have them and don't want them, then many people aren't really interested in being around them. You do get that is exactly why 55+ communities exist and they are protected under fair housing, which means it isn't anything abnormal at all. Now it is our job to not promote that in communities that don't have that distinction, but if you can't at least be empathetic to people under that age who really aren't excited about kids and would rather not live around them, you might not grasp life. I have pets and kids, but I can completely 100% get someone that wants a quiet life away from them. Adult only resorts also exist specifically for this very reason. Someone that chooses their own life removed from children shouldn't make anyone uncomfortable at all. I'd actually encourage anyone to hang out around the property and see if they feel like it's vibe in general is going to be a fit for them.
