What is wrong with discussing politics?

So many colleagues and friends make it a point of being off-topic.

Don t you think it s better to communicate with each other? We are stuck with these governing bodies to protect us and add growth . Only 1 rule if you make a claim against another, then you must be able to fact verify first hand and not a social from a social media platform.
Thoughts, comments or ways to get communication going for the best?
