Sure, minority issues are often limited to minority communities. I don't read r/publicfreakout either, but as a moderator of r/Jewish I can see the impact it and many other subs have on our community. You have your standard malicious crossposting and trolls, which we have good enough ways to deal with. Antisemitism from other subs leaks and grows and we often get brigades of intactivists, conspiracy theorists, BHI-sympathizers, you name it. Reddit's new Crowd Control system helps but it's not perfect. Good luck if anything happens in Israel (which it frequently does), you may as well just shut the sub down for a day.

Reddit shuts down other kinds of hate, the double standard is glaring. The fact that it doesn't impact you personally is so not the point.
