You are free to block communities or even whole instances if you want.

I don’t particularly care for the anti-western hegemony, anti-capitalist, attitudes from a minority of users there that can’t help themselves but make every post political but i still enjoy the content from the rest.

The health of the network depends on being able to have a lot of different viewpoints and servers federated which each other. It’s better for users to block content and users that are bothersome to them than admins to defederate for political reasons (harassment, legal and liability issues of course are reasonable still)
