I feel conflicted with this view. It feels partially like something social media giants would advocate, the idea that their little social media platform is some special community where people are different and normal open web rules shouldn't apply.

I feel the philosophy of posting on the web and hosting your own website is that the web is the community with which I want to share my thoughts. If I just wanted to share my thoughts with just one platform/community, I would go and just post it on that one platform, I wouldn't go to the trouble of running a website.

I get that it's important that there's safe spaces, and some communities should be like that (essentially, private but online) but that view should be the minority and exception for edge cases, rather than the default view of all different websites or platforms.
