This can be used to justify anything. Muslims and Jews used to be persecuted in catholic spain for a very long time since the 1400s, should muslims make periodic month-long parades where they play the quran loudly and cosplay as 14th century muslim warriors ? should Spain be forced to host them ?
"I was harmed in the past" is suspiciously similar to what a lot of abusers and opportunistic psychopaths say to justify their actions and get their way.
>with the expected goal being to ward off further persecution in the future.
How does that work ? Some people despise your existence, so you... shove your existence in their faces and in their streets even more ? To what end ? own them ? stick your tongue out ? rub your legal or social victory in their face ? This is just plain revenge, you can just call it "owning the haters", no need to add any kind of moral decorations on top that isn't there.
This would make you more honest, and also open your eyes to some effects you're not currently seeing with the overly moralistic framework, such as that the "owning" might be overly broad and end up making people who previously had no problem with the group in question gradually resent it more and more as it intrude further into their life year after year.
Regardless of its purpose or morality, is this strategy even successful ? was it used in the past by any minority that successfully evaded the majority's wrath because of it ? if anything, majorities hate proud minorities even more. Is there any coherent defense of it that lays out how exactly is obnoxiously marching in the streets supposed to make people accept you more than they currently do ?
