That is the same bahviour Trump shows when he retweets racist stuff. Both are unacceptable. The difference being, The MP you mentioned is part of the minority, and she deleted and the retweet and ecused herself. The article also discribes the original tweet coming from "a parody account" from a journalist.

So, you just confused the opposition, it is a Labour MP after all, with the government. And you totally ignored the origin of the retweet and the fact that the MP in question re-tweeted and did not write that tweet herself. Nice job, really.
