It's this type of bigotry which is the reason I refuse to post any more threads in this forum.
I'm tempted to say that opinions are alright as long as they are clearly presented as opinions. People with opinions should make an effort to not derail discussions, and in return, they shouldn't be hounded for proof. Assertions on the other hand should only be made if you can provide evidence for them.
What's the real difference between an opinion and an assertion?? if a person believes something to be true then clearly it's also an assertion otherwise they would not believe it to be the case and would not believe it in the first place.
What you are saying is that everyone needs to write the words 'In my opinion'
in front of every single post they make.
