FTA:

According to the Democratic caricature, most Republicans stridently oppose immigration, hold deeply prejudiced views about religious minorities, and are blind to the existence of racism or sexism. Asked to guess what share of Republicans believe that immigration can strengthen America so long as it is “properly controlled,” for example, Democrats estimated about half; actually, nearly nine in 10 agreed with this sentiment.

Democrats also estimated that four in 10 Republicans believe that “many Muslims are good Americans,” and that only half recognize that “racism still exists in America.” In reality, those figures were two-thirds and four in five.

Unsurprisingly, Republicans are also prone to caricature Democrats. For example, Republicans approximated that only about half of Democrats are “proud to be American” despite the country’s problems. Actually, more than four in five Democrats said they are. Similarly, Republicans guessed that fewer than four in 10 Democrats reject the idea of open borders. Actually, seven in 10 said they do.

This country will heal once enough Democrats wake up to the fact that their party has turned its back on this country. The Democratic party needs to be vanquished. Only after this happens and a more sensible party emerges to be the new "2nd" party in this country can healing begin.
