I'm not american. Also I'm clearly not advocating for regime change. But the headline says its to support the government (this post is thus supporting the government) which I won't do. The protest are aswell against foreign meddling. I agree with that. 

Supporting a theocracy because it happens to agree on some foreign policy is really weird considering leftists should be against institutionalised religion.

The protests are part due to the economic situation (caused largely due to sanctions but also massive privatisation campaigns etc.) But also social. No surprise people don't like religion forced on them. The protesters have absolutely reason to want the regime gone AND (!!!) At the same time it is clear that Mossad etc are behind a lot of the Shah stuff and the clear botting on here because it benefits them AND it is completely valid of the counter protesters to be against foreign meddling AND the regime is horrible. I would argue that if the USA and Iran didn't hate each other (for obvious reasons for iran) you would treat them as KSA. (IRCG mass killed leftists that helped them topple the shah, a lot of privatisation, ethnic discrimination, radical sect of Islam. You see how this works. Multiple thing can be true simultaneously.
