Individually they were probably no threat, except they will more than likely try to haggle the price after agreeing one or find a reason not to pay altogether.
However it's what they represent. Though as a liberal who just throws insults around you definitely won't see wholesale import of millions of stone age mysogynistic, homophobic members of a death cult as a problem. It's not for nothing that Portugal and Spain expunged them several centuries ago. You've learnt nothing. I have nothing to do with them at all.
