How about this:
You cry about echo chambers, and I'll enjoy talking to people very different from me, from a range of genders, countries, and backgrounds, where the only common ideas we share and echo in our little chamber, are "Trans people exist, leave them alone." and "Women have rights, respect them." and "Racists don't deserve our time."
No sarcasm on this one. I'm very serious. "Sounds like an echo chamber!" is not a statement I take seriously.
