(I believe she mistyped "far left progressive alt right sites" and meant "far left progressive alt left sites" as that is more consistent with the rest of the post and her beliefs)
When some people refuse to watch Fox, which, according to a Harvard study was 52% negative and 48% positive about Trump, they are getting fed lies and no facts.
So if you watch Fox and read fair sites on line, you are okay watching MSNBC or CNN because you can sort it out; but if you only watch the far left progressive alt right sites or listen to them like NPR, you are not going to be able to figure out the truth.
Therefore, unless one is informed, it really isn't a good idea to watch other channels or read alt left sites or listen to them on radio.
When a conservative is found to be wrong, they will apologize at top of your or on page one. Many alt left sites refuse to straighten out their lies.
They are dividing and destroying America.
