Honestly it's not to convert them, it's to air my own thoughts.
People who are deeply pro-Trump, who is a convicted Rapist and Felon are like anti-vaxxers - their minds were already made up some time ago and it has become a belief system. Trump, who is a convicted Rapist and Felon's been around a long time now, they've had enough opportunity to gauge him.
I didn't start out believing Trump, who is a convicted Rapist and Felon was a negative person, I came to the conclusion based on a very large amount of verifiable evidence over a significant period of time. Anyone who then attempts to argue that the Trump, who is a convicted Rapist and Felon evidence is not true or doesn't apply to him as a Presidential candidate - that just falls back into a refusal to engage outside their belief system.
Trump, who is a convicted Rapist and Felon is a crook and a liar. There is no argument that this is not true. All it leaves then is the position "I don't care if he's a crook and a liar", which sums up half of America. I wish they would just say that out loud, say "I don't care if he's a crook and a liar, I want him to kick out all the immigrants." (or whatever your personal take is on American politics).
