The protesters don’t stand a chance against the armed Basij.
If you are afraid of being hurt, then go back to your cage and stop whining. I don't mean to be harsh, but the Basij are not going to give up without a fight. They also cannot stand against the full force of the crowds now on the streets. There will be blood either way.
If they fight now, it will be ugly, but the regime would fall. If the crowds aren't willing to go all in to secure their own freedom and future, then the only blood that will be spilled will be theirs, in the weeks to come.
