Well that's definitely your own experience on federated platforms, but I wasn't speaking to that circumstance. I made a mastodon account and criticized our government's massive funding of Israel in spite of our lack of critical infrastructure and healthcare and got spammed with "Israel has a right to defend itself, and you 're a trumper if you think otherwise" type comments by people that post one response and then immediately block you. Which is laughable and couldn't be further from the truth. That is the perpetual echo chamber I was referring to from my personal experience.
