Opinions are always valid ... even when they are based on whims, irrationality, nonsense, lies ... they are personal - very personal - and everyone is entitled to have them; yes, even if you don't agree with them.
It is fully within a person's rights to be allowed to have and express their thoughts in the form of opinions. It does not have to be your business ... and you do not have to make your goal in life to have an opinion on everyone else's opinions.
