Get a platform for non-frummer people of faith. They are out there but they don't have the bucks or media influence to combat in the giant, out-there way. This will provide an alternative for spiritual seekers (so they don't get sucked into frummerism, thus decreasing frum-ranks), provide good counter-arguments for each bit of frum-insanity & take the wind out of the frum's propaganda-sails.
Concerning Islamo-frummerism, it's all over the place because Wahabiism is HEAVILY-funded by Saudi Arabia! It was invented by Saudis to discredit & destroy more kinder, saner forms of Islam. They have tons of Wahabi Madrassas & mosques and for many young people in bad situations, it's the only Islam they know. That said, Islamophobia is not the problem, Wahabiism is. Same can be held true for sane peaceful Christianity vs. ChristoFrum Puritanism. Frum-religion must be wiped out!
A great way to combat a corrupt group is for a non-corrupt version of said group to speak out against it. Same holds true for men standing up for women's rights. If the majority of men & boys were vocal about the rights of women & girls, misogyny would die out faster.
I also feel that the concept of "The Demiurge" needs to be introduced to all faiths and not just be seen as a strictly "Gnostic" thing. The Demiurge can be seen as either a literal or metaphorical "Spirit Of False Piety" & "Devil of Frummerism". Any scripture that espouses anything condoning Ethnicism, Sexism, Homophobia, Rape, Genocide, Ableism or any other malevolent "Ism" will be dismissed as "Demiurgic" & therefore heresy & delusion that can be rejected.
In the end, though, I think scriptures are "all vanity" & that reducing The Divine to a mere book written by human hands is dumb & pure hubris. Since people are bound to follow Organized Religion, however, this is the best we could do.
