You misuse "cherry-picked" which means to select specific incidents not representative of the typical to give a biased, unrepresentative picture of the average or typical incident.

This has nothing to do with Trump.  Tolerance and respect are universals.  The problem is that these dudes make it about Trump and thus not about tolerance and respect but politics and personal preference.  They demonstrate in their writing exactly what they are admonishing others not to do.
