Virtually every value liberals have held for a century is now held by conservatives and scorned by leftists. Therefore, America, in serious jeopardy of being lost, will be saved when people convince the liberals in their life that the left, not the conservative, is their enemy.
This process begins by establishing whether a friend or relative is a liberal or a leftist. If it turns out that he or she is a liberal, it is worth engaging in respectful dialogue on the issues of the day. If the friend or relative is a leftist, you can probably only talk about innocuous subjects such as the weather (though not about global warming) or sports (though not about players taking a knee during the national anthem). If you talk about the great issues of the day with a left-wing friend or relative, that could be the last time you talk to each other. He or she is likely to unfriend you not only on social media but also in life. Leftists generally do not dialogue; they dismiss.
