Unfortunately, facts don’t mean anything to the type of people who are supporters of Palestinians. They tend to be leftists and irrefutable evidence of anything they don’t agree with won’t change their minds. They ignore reality. One time I was discussing something with a liberal relative and showed her something that disproved her argument and she told me she didn’t care if it was true or not, she wanted her belief to be true. Trying to convince someone with that mentality is a fool’s errand.
