There's also the first amendment. I don't agree with what the teachers are doing, but your response is deeply troubling.
The first response of authoritarian governments, fascists, and dictators is to immediately arrest anyone who speaks out against the government. And then you don't want the government to deal with them, you want to also look into the DNC because.. idk... hatred?
Remember the Bundy standoff? Armed militants forcibly and illegally taking over government property, literally pointing assault weapons at government agents???? Did anyone say, hey, the justice department needs to investigate the RNC???? NO.
Little bit of an overreaction on your part.
First, the First Amendment doesn't protect speech meant to incite those hearing the speech to do harm to others.
Second, I didn't say to investigate the Democratic Party, I said that given the ties between the union and Democratic Party that it should be dealt with by the Justice Department. Meaning very simply, that a group which is trying to do harm through others could be a danger to our political system and given that group's close tie to one of our major political parties and therefore by inference that any investigation into this shouldn't be accomplished by Department of Education, nor the Department of Labor, nor the National Labor Relations Board, nor any other federal agency other than the Department of Justice.
Third... The Bundy's? You equated the anarchical nutjob Bundy family that has no power, to labor unions that have unquestionable control over major parts of the Democratic Party? Since when did the Bundy's finance political campaigns to the level of the unions, or that the Bundy family has hundreds of thousands of members across the country campaigning for Republicans like unions do for Democrats, or have they protested against sitting Governors and many, many other Democrats in government the way unions have against sitting Republican Governors and many, many other Republican government officials?
Seriously? The Bundy's?
Fourth, it is unquestionable that the union by it's own words and intended results of it's actions is using it's power to undermine the properly elected legitimate government of the United States of America by inciting rebellion and insurrection. Did you even read the law at the links I gave? I tend to not think you did. Please read the first link and then compare what it says to what the OP article says that the union is actually doing. Any fair reading of both cannot legitimately come to any other conclusion other than that they are related one to the other.
Fifth, the Bundy's? I know I've said that already, but I thought it important enough that it bears repeating.
Edit: I forgot to address your accusation that I would post such a thing out of hatred. No, it isn't hatred. It's patriotism and the oath I took decades ago to protect and defend the Constitution.
