Also it's largely pointless. Unlike technology arguments, where you can easily convince me to try switching from Sublime to VSCode or to give Rust a try instead of C++, etc. political beliefs are much more entrenched. Each side has a very hard time understanding and empathizing with the viewpoint of the other side.
Exactly, it's a lot like religion, except that at least with politics you can at least attempt to bring facts and data into the discussion in an attempt to disprove the other side's points. But people still treat it like a religion so it generally just isn't productive to discuss it, unless you're among people who are generally like-minded, and you're only hashing out finer points (e.g., would policy A or policy B be more fruitful for reducing global warming? Rather than arguing over whether global warming is real or not).
