In other words, people have always been this way and the internet just gives them a more visible platform to express their bullshit.
Well, I'd say no...people were not always this way. Yes, there was always "the town busybodies" and many an old movie has had them as prominent figures of ridicule, as they should be.
I firmly believe that the internet has allowed two very important things to happen; 1) it gives the armor of anonymity where you can say pretty much anything (more on that) without having to stand up in front of people who know you and who can question your judgements and 2) it makes people feel like their opinion matters; just their opinion; nothing to back it up, no logic to sustain it, no reason other than "I think it should be this way" (and that is usually because they are just following along with the crowd they hang out with).
Back when people had to get together and speak their mind or had to write to the paper with their opinions AND THERE NAMES, you didn't have that ability to hide behind anonymity; you were Bob, the auto mechanic on 1st and Penter Ave. stating what he saw as an issue with the closest fire department being located 25 minutes from his part of town. Now, it's just a bitch fest and everyone has a horrible, disgusting entitlement mentality that reduces them to no more than whining infants.
"Movements" and "causes" can also give people (heards) that same sense of power, without mindful, thoughtful direction. We see this today.
Oh, and as far as "saying pretty much anything", it is almost universally true, in my experience, that such latitude is only granted if you want to say what I want to hear. If you want to say something contrary to my "beliefs" (read "my take on the current in-vogue sentimentality"), then you should be censored...

As a sad note: I did a search for "nazi salute" on Giphy for the above...almost every one of the 100-odd gifs was a variation of the American or British military salute (with a Roman and US Scout salute thrown in). Not a single Nazi salute. I tried several other variations on the search words with the same results. We have been cleansed by popular media of the reality of our past because those who have/want power over your lives know that knowledge of history empowers you to avoid repeating it.
BTW, I had to search outside of Giphy (think I'll avoid them in the future).
For those who are curious, I am not Jewish but I see the same tide rising, just for a different group (though, the Jews would, I believe be, once again, included in the purge) .
Sorry,
@mrblaine, guess that went a bit off-track...maybe.
