They believe the left not tolerating their "different opinions" cancels out their "different opinions" of not tolerating people because of their race, religion, gender, sexual preference, etc.
A sizeable portion of the modern Left definitely say that believing in the concept of borders and controlled immigration is intolerance – and thus unacceptable – but fail to see that it is an opinion, not a fact. This is one area where the modern Left nears actual fascists, by (conveniently for them) labelling some arbitrary opinions as “invalid”.
Another opinion is to call it intolerance to have doors and locks in homes. What, you don't tolerate trespassers there? Should that intolerance be tolerated?
You're attacking imaginary straw men. And you're throwing around words whose definition you don't understand.
Instead of stereotyping and attacking large diverse groups of people like you're attempting to do, let's talk about someone who really exists, and whose words are on the record, not a hypothetical subject for debate.
Calling Mexicans "rapists" is intolerance.
Do you tolerate people who brag about grabbing women by the "pussy"?
Is the opinion that you can get away with sexual assault if you're rich a valid opinion?
No I'm not (on both counts). But you're switching the subject... (There is nothing to be gained from this discussion, not that I didn't know it from the start.)
