Secondly, in my country due to the law, if you make unproven claims in your reviews on Google Maps or other public spaces, Google has to take the review down at your request and you can also get sued for defamation, so unless you have receipts you gotta be careful what claims you make in public about someone, especially when you call people alt-right.
Like I said, innocent until proven guilty, especially if you're gonna make wild accusations like that.
The boy who cried wolf comes to mind. If you go around calling everyone who disagrees with you "alt-right", that term looses it's meaning and everyone becomes desensitized and won't care anymore even when actual right wing behavior shows up.
