The girl (and the father) had the typical emotional 'warble voice' of a liberal.
As if they were about to break into tears.
In believing they are right,
and that there is only one way to think,
one truth,
The shock of having someone say "Nope, I don't agree" is more than they can handle.
Add to that the fact that many can do no more than quote word for word (almost cultlike) the 'teachings' of their esteemed ones. Don't ask for opinions or critical thinking. They can only quote. No independent thinking allowed. And that's what the socialists are counting on.
And of course, (I never tire of this!) if you do disagree or ask them to explain, you get the famous whine, "You just don't get it....". (It's almost too easy and fun, too.)
