When you ask questions, that is one reason why they won’t answer.
Another reason is that they do not know the answer as to why they believe what they believe or can’t justify their belief with any reasonable, believable, or rational answer.
It's because the people who promote socialism the most, know it's a con job. Under socialism, the leadership live well, and the people eat trash. Socialism is a way for people who are articulate, but not very good at actually producing anything, to get power.
But they won't admit it to YOU.
