Sure, mainstream opinions may be wrong, that often happens. However, they're still mainstream opinions, not a few rare extremists that can be just pushed out to edges and excluded. So you can disagree with their wrong opinions, and work to change their mind, but until they do - and even if they don't - in the workplace, you have to be able to work together with people strongly holding those wrong opinions; however wrong these peoople are, they should have equal rights to you. (I mean, weren't you also suggesting throwing out some people off workplaces because of their views?) And one definitely can advocate for tolerance for the intolerant as well - IIRC Jefferson explitly argued that we should, Popper argues that it won't turn out well and we shouldn't, I'd probably argue for something like John Rawl's position which is essentially tolerance up until actual imminent threat to physical security or perserveration of key institutions, i.e. intolerance of intolerant only as an extraordinary measure, but there are many reasonable arguments about this, there's no consensus agreement on any solution to the paradox of tolerance.
