I understand about calling you "Big Momma". Someone needs to know you well enough to know if you are ok with it before using names like that.
It is always best to start out with someone you don't know with politeness and good behavior. There is too much rudeness in general these days.
As has been pointed out by pretty much all the comments on here, there's definitely been a huge change in how people connect (or fail to) with each other. I kinda wish I was over 18 in those supposed early years when people could make connections, but my impression of social networking is that of people being less accepting of others' differences. With echo chambers, one-click shopping, and the draw of individualistic "hustles" like YouTube, Patreon, OF, scamming, etc., all being more-widely facilitated by social networking and other websites, it's probably easier than ever for people to care less about connecting to others and focusing on getting/pursuing what they like. This speculative theory of mine suggests it's more unfortunate than unsurprising that Feedism communities like this one are affected by increased individualism, reduced empathy, and implicit bias. And yes, by "implicit bias" I mean racism, but I also am describing the other biases that lead people to give disparate attention towards others, like the aforementioned blonde, tall, or "male/masculine feeder--female/feminine feedee" biases.
(Without making a virus allegory) I believe an online community is not immune to the social dynamics or cultural changes that users experience or are affected by, so it's possible the struggles of fetish communities have external sources in addition to internal sources.
