You can never allow someone who can be proven a liar on so many levels to be given a platform at schools. If there is evidence—and loads—that make everything he says a lie—you do not allow him to speak to CHILDREN. They absorb the lies as well as the truth....which creates cognitive dissonance—exactly what cultural Marxists want so we have illiterate OWS and ACORN thugs.
Insertion of known lies into debates create irrational thinking.
It is one thing to debate ideas—but you don’t allow outright lies to form the basis of the debate.
As I said. Teach your children well.
Unless we expose our children to those who speak lies, they will not know if we speak the truth. Kids are smarter than you think.
