An anti-Israel British Filmmaker tweeted the following about Breaking Bad actor RJ Mitte:
It was amplified by others.
While it may not have been her intention (but probably was), the tweet implies RJ is anti-Israel, given the keffiyeh can be seen to be a symbol of palestinian terrorism.
I am happy to report this is almost certainly not the case.
Assuming his shirt is a “keffiyeh print” to begin with, I posit it was not a political statement.
For a start, RJ is associated with the Ruderman foundation

The Ruderman Foundation is deeply Zionist. Besides “Disability Inclusion Advocacy”, the other type of advocacy mentioned on their website is “Israel-American Jewish Relations.”
A hater would never have tweeted this.
So don’t be fooled by those trying to mislead. This was not a case of Casey.
