Whereas the other candidate is point blank saying that he would deport millions of people, jail opponents, let police do whatever they want, use the military in illegal ways - I can't help but think that you call that "free world" and want to make up a scare about "communism" because of your own political bias.
Deporting millions of people that Kamala has been quick to let in is fucking cool. The jailing opponents thing I understand is for committing crimes following legal procedures (many Democrats also want to put Trump in jail) and if you want me to answer what I bolded provide some links because it doesn't ring a bell and I imagine you are distorting something he said.
If I recall correctly, since Joe Biden started his first term there was indeed a sentiment in immigrants about having an easier path to cross the border illegal and apply for any benefit it was granted to them while waiting for asylum or permanent residency. I have myself seen documentary films on people seeking to cross to the USA and they wanted to do it as soon as Biden got into office. On the other hand, it would be a lie to say there were no illegal crossings during the First rump administration, but they were probably lower but they were handled in a similar fashion, as immigration laws continue to be about the same, regardless of the color of the party in power.
Trump does not have a magical formula to deal with immigration, he never had it and the border wall he talked so much about in 2016 was rather a strategy to fuel and direct the frustration of an important percentage of the population of the country.
Even if he wants to make something dramatic to change things, like mass deportations the laws put in place and the fragmentation of power within Washington will prevent him from doing anything effective. It is similar to that occasion he wanted to ban people coming in planes from muslin majority countries. It was reversed by a judge.
