This is one drawback of forums. Often and it's only right, we don't have the full story because the full story will never be told.
So I'm merely going by what I "see" here, based on her words. Once "racist" is spoken, it raises all sorts of negativety and that's only normal. So maybe it's not all that serious. But maybe it is. Who's to say? Really.
But as a retired Paralegal constitutional offenses, even if not serious in my/our minds, based on personal experiences though such experiences may be subjective, raises alarm.
Thus my merely suggestions, which I do and will stand by, no matter the disagreements.
