What derogatory nickname? Is that anything like Cruzers?
It’s often used as one.
‘Cruzers’ started to be used respectfully, but it seems nowadays to be used to slam. Same with ‘Trumpers’ or ‘Trumpees’ or whatever.
I prefer to use ‘Cruz supporters’ when trying to speak respectfully just so it can’t be misinterpreted.
Of course, when dealing with trolls, respect tends to be the first casualty, so I freely admit to flinging out insults too. In my defense, I try not to be the first to fling it out. Tough but fair.
