I also didn't say anything about racism, you made the link between my earlier comment about "racist rhetoric" and southern border crossings on your own. "Racist rhetoric" that I'm thinking of is the implication that someone disliked by GOP candidates is "illegal", even though they're not breaking any laws an have legal status, e.g. Springfield Haitians. It may be tempting to think "this is a gray area, matter of opinion, no big deal" but it creates a growing perception that immigrants are often or mostly illegal, which couldn't be further from the truth and creates real dangers, such as the recent bomb threats in Springfield. It's rooted in misunderstanding of how immigration works and exploited by scumbags like JD.
Well, that would be for starters assuming the official statistics are correct. Statistics can be used to debate but they are far from being firm, not only because some statistics contradict others, but because I am sick and tired of seeing debates in which opponents use the same statistics to defend the opposite position.
Before I also wrote an answer about what you argue about legal status that among the quotes I do not know why in the end it has not been published (I must have made some mistake) but I came to say that the legal status thing is very funny, in the end what Kamala does is to facilitate that you can get a legal status by applying as a refugee even if you do not come from a country at war but if you are a plumber who comes to seek a better economic future.
By the way, I don't want to personalize too much but it sounds to me that you said in a comment (years ago) that you had lived in a communist country. Is that so? If you are an immigrant in the USA I would understand your position more, although you don't have to answer this if you don't want to, of course.
