You are not making any sense now.
NDU is free under the Constitution to decide
that pro-aborts are NOT trespassing on NDU’s private property,
and that pro-lifers ARE trespassing on NDU’s private property.
What is it that you don’t understand?
You are correct to note that NDU was stupid to do so,
but that does not make it illegal or unconstitutional.
In fact, your views are very dangerous because you are advocating that private property owners cannot control who has access to its private property.
You’re adding to my words. You really shouldn’t do that.
