Rule review - feedback request

In https://lemmy.world/post/50116148 , I asked for ideas on how to improve the rules.

The 3 pieces of feedback I received:

1. should we have a “no mass downvoting” rule? too often I see an unpopular opinion post where every OP comment just gets blanket downvoted despite very much engaging in good faith - 2 upvotes, 0 downvotes
2. I just wish people upvoted unpopular opinions, instead of the opinions they agree wirh. Anything people don’t agree with, they downvote. :( - 18 upvotes, 0 downvotes (not sure if this is something we can easily turn into a rule)
3. Remove no politics rule. Let’s get some political unpopular opinions - 4 upvotes, 3 downvotes

Let me know what we should change from the list above - if anything.
