You advanced no argument. Instead you simply asserted moral equivalencies. Explained below.
So you think Trump is the first politician to make overtly racist comments? You haven't really been paying attention to politics, have you? Notice these are questions. Nothing follows from questions because they're not propositions. Accordingly, this is not an argument, where a conclusion is supposed to follow from or at least receive support from premises. The best I can see here is an attempt to minimize the fact that Trump--the current president of the US--didn't do anything that perverse because some unnamed politicians somewhere at some time in the past made a racist statement. Find a recent president (not some random politician) who, while in office, said something on all fours with this. So this is the initial set up for the moral equivalence move: "Come on guys, this is something we see everyday. Nothing to see here."
Trump's comments were wrong. I don't think he necessarily meant them to be racist, but they were poorly worded, uninformed, and idiotic. He won't do it, but he should issue an apology. That doesn't change the fact that the 4 congresswomen he was alluding to are full of themselves and think they know more than they do.
Not seeing an argument here. What's the conclusion? The best I can see, in short, is Trump was wrong, but these women have big league hubris. This is the moral equivalence move. After trying to minimize what Trump said so it doesn't seem so serious (first paragraph), you try to link what he did, causally, to what they've done, and roughly equate the two. It's like Chris Rock on OJ Simpson: "Not saying he should have killed her, but I understand."
Our country has problems and sadly most just want to point fingers and place blame rather than find real, viable solutions.
This point obviously has no bearing on whether what Trump said was racist or not. But it is another attempt to minimize the event and change the subject--a classic move after making the moral equivalence point. "A happens all the time, and it's really no worse than what the other guys did, and besides, don't we have bigger fish to fry. So let's not focus on what Trump said and just move on."
