Realistically until we can move past religions its not going to stop. When you create constant in groups and out groups you are going to have conflict and blame wars. Until we can view each other as equals and for that to happen either everyone has to be under the same religion or we accept religions were a terrible form of government that need to be abandoned. And then we might just see rampant racism at that point if education is not properly funded and supported following the fall of religions. Then it would be nationalism until we can globally unite, and then still we will run into small groups of uneducated people who will be easily swayed allowing these bullshit issues to propagate again but hopefully not at the same level. Not that it’s reassuring but we have massive issues that need to be addressed for this shit to end and as billionaires profit from uneducated laborers, until we get to post scarcity for our species I don’t know if it will end.
