[[Why is it so difficult to support Trump without bad-mouthing Cruz?? And vice-versa?]]
It’s an age thing and a lack of maturity thing-
Because we are no longer politically correct. Political correctness is DEAD.
Your comment sounds like Rodney King’s “Can’t we all just get along?”.
Bad mouthing is just fine if what is said is true and/or the person deserves it.
“TRUTH” will set you free, but it might hurt your feelings. Get over it.
