A lot of what is attacked as anti-semitic is openly spoken about in the Jewish media. Everybody should subscribe to outlets such as The Times of Israel. If you do not wish to read it for the news content, it certainly is educational. Many issues that are only now being discussed by the general public have been an issue for years. Take this article from 2014:

The debate over whether being Jewish is a requirement for the presidency has “never [been] more fierce than it is today,” said Jerry Cohen, a longtime American studies professor at Brandeis who is working on a book titled “Innermost Part: Brandeis University and the Jewish Question.” “This question, whither Brandeis, is now up for definition and debate as we contemplate a new president, trying to figure out where we are and who we are.”

The current high number of international students — the figure has risen 30 percent over the past five years and now comprises 18 percent of undergraduates — is something of a fluke that is in the process of being corrected, said Andrew Flagel, the senior vice president for students and enrollment.

It's in the process of being corrected! Also, there is no discrimination against Asians (actual Asians, for British readers) at America's universities. Such anti-semitism! Especially that Jews would engage in such behaviors, after having been victims of discrimination for so long! Unthinkable.

The supposedly most virulent anti-semitic opinions being condemned by western media are frequently completely mainstream Israeli positions.

Just start listening to their own words. All you need to do is repost what they say and when you are inevitably accused of anti-semitism, link them to the original source. They will shut up.

Also, the Jewish media are already in support of the walkout:

Thousands join 48-hour Twitter ‘walkout’ to protest anti-Semitism on platform

The grime musician, who has half a million Twitter followers, was given a seven-day suspension from the platform. Amid a wave of backlash his management company said it had cut all ties with him. He is also facing a police investigation.

It's complete nonsense that anyone supported those messages simply because they didn't remove the posts with a speed that was to the liking of the perpetually offended. It's an absolute media circus, complete with the usual smears, lies, false allegations, purposeful misinterpretations, distortions, and fact-free arguments, character attacks, deployment of authoritarian power and intervention. These supposed victims have the power of all of the establishment behind them. What is painted as some sort of grass root rise against the oppression of hatred by the powerful and the elite is the complete opposite: the silencing of dissidents whose opinions do not align with the majority.

If you want to help fight for truth, you will use the supposed time of silence on Twitter to present the facts of the matter and support those who speak honestly. But, I can hardly imagine that the chattering classes will manage to keep quiet for 48 hours. That would be too good to be true.
