I'm still trying to wrap my head around this one... a yogurt attack? Like, what even is that?! 
It's just so... random. And the fact that it happened at a supermarket, where you'd think people would be chillin', makes it all the more messed up.It's not like this guy was defending some kind of honor or tradition - there were no protests, no chants, no signs pointing to any particular ideology... it just seems like a random act of weirdness. And now these two women are dealing with the aftermath, which is super uncomfortable for them and their loved ones.
We need to talk about why this guy felt the need to lash out like that in the first place... was he just trolling for attention? Was he trying to send some kind of message? Whatever it was, it's not okay. And the fact that we're even having this conversation in Iran, where women are already under a lot of scrutiny about their dress code... it's just another layer of problems to unpack.
they need to chill out and respect everyone's choices, regardless of their outfit

i'm not buying the "social and cultural pressures" excuse, it sounds like plain old fashioned misogyny 
we should be supporting women who are confident enough to express themselves freely, not shaming them into submission
