Sandra, relax, there's an old mantra and it goes: don't feed the trolls! The worst for trolls is no reaction, no response at all. Trolls feed on replies. Simply don't give them the pleasure. Ignore such trolls'n'clowns and they'd starve and have to play with themselves. Easier said than done, for sure...
To tell you this ol' rule, unfortunately I have to violate it.
