Philosophy should not be used to justify regular human actions, and non-scientists should not expect their crank-adjacent theories to be taken seriously in the respective science communities. We don't need awful people running around calling themselves 'solipsists' to 'explain' their behavior, and we do not need Marxist-Leninists and Trotskyists popping their heads into debates about the Big Bang Theory or whether electrons exist

white people should be banned from spiritualism

Weed sucks and should be forbidden just like cigarettes, vapes and etc.
