Some of the core/foundational requirements for a group to exist, and continue to exist, regardless of the group's size or context, is for people to congregate with whom they choose, to be able to protect itself, to be able to protect its borders, to gatekeep out undesirables, to enforce its own culture and heritage upon that group, for the good of the group. If these basic tenets for group cohesion and survival are not followed or disallowed, it means that group will inevitably be destroyed by diversity, by people who do not belong in that group. It's tantamount to an invasion. No matter how slow the process takes, the results are always the same.

People are having to relearn these lessons, because we've been propagandize since birth, lessons that our ancestors knew so innately that they never needed to write about or discuss them. They could never conceive of lies so blatantly egregious to reality that anyone could believe them.

Fortunately, this has resulted in increasing numbers of people becoming ardent and unyielding gatekeepers of their groups. The cries for "inclusion" by the egalitarianists and multiculturalists are falling on deaf ears by these newly zealous gatekeepers, who no longer seek appeasement or compromise from people who would destroy them and everything they love.
