I understand the idea of just focusing on the code and leaving politics aside. Sadly that is not how it works.

Those statements are necessary so people know it is safe to engage with this community. So women know they are less likely to be openly harassed and demeaned. So trans people know they are allowed to exist in this community. So that black people know they will not be bombarded by racism.

An yes you have to be proactive and drive out Nazis or they will take over your community over time. You can not tolerate those that show intolerance.

Choosing to "not be political" means choosing to be inclusive to Nazis and to be dangerous for nearly everyone else.
