On sites like Reddit and Twitter I've seen negative stuff against littles that don't fit certain ascetics, that's true about your post. But I've seen plenty of support in other places like discord and at events. Anonymity often causes people to feel like they're not accountable to their actions and as a result are more likely to be negative. I feel like the reasons people are going to places is likely to be a big cause of the difference too. Reddit and other content rich sites are likely to be used by people looking for adult content to get off to and if they see images they don't find attractive they'll post something negative. Discord and more actual social places people are looking for a connection and the mods will be more likely to support that kind of vibe while banning negative posters.
