So by your logic, one's heart can only change for the better? You've been defending Trump's liberal track record (being pro-abortion, anti-gun, anti-deportation of illegal immigrants, etc...) by saying he had a change of heart. Fair enough, but couldn't one argue that since Donald Trump has changed on so many fundamental issues, his sentiments of minorities is one of them?
By the way, I don't think Trump is racist. He does say things without thinking and give the appearance of prejudice/racism though.
