The Left isn’t happy unless they are waging some sort of jihad against the symbols of hate. The Washington Redskins. The Confederate flag. “Trigger” words like “success” or their perceptions of racism, sexism, ageism.
Their energies, for a long time, have been focused on gay marriage. That battle is over but their next battle will be forcing religious institutions to marry gays and to threaten to strip their tax exempt status if they fail. The Left will keep pushing but this next battle will require even more rhetoric and astroturfing. And it will likely turn a lot of Americans off.
Saying that everyone has the right to marry is a message that sounds fair and thus many people can get behind it. Saying that religious institutions are bigots and hateful and should be stripped of their status is something else.
As the low hanging fruit is eliminated, Leftists will have to go after more and more things and, eventually, they’re going to go after things that people really care about and, finally, the “silent majority” may rise up.
