I tend to have strong opinions, but one thing I find fascinating about praxeology is that it doesn't judge, it just studies why people act the way they do. As soon as a judgement or opinion is pushed, it ceases to be science.
However, it does attract libertarians. I think that's because it reveals facts in a cold, logical, objective way; facts tyrants love to hide - by appealing to emotions, propaganda etc. Once the facts are revealed, people can see things in a different light and form their own, better informed opinions, regardless of where they stand emotionally.
