Not raising one's kids definitely helps, if you don't someone else will.
That said blaming parenting styles is tough because in a lot of cases there's nothing a parent could've done. They simply don't have the resources or community necessary to raise children without malicious outside influences getting to them, and the world has changed so much so quickly I don't know if it's even reasonable to have expected any of them to have seen it coming.
If you're a helicopter parent your kids will wind up being helpless and falling into it more around college age, and if you aren't they'll get groomed into it earlier. Without finding a proper environment, there is nothing a person can do that will stop it.
I grew up on the internet in the late 90's and early 2000's unsupervised. That was a wild time that could let you turn into any kind of degenerate. The modern internet only lets you turn into one type of degenerate that offends my sensibilities. I'll make my kids Judas Priest's (Jehovah's Witnesses.) before I let them become commie turd burglars.
I homeschool. It's the only way really. Otherwise you are throwing your children into a hive a hive of villainy. Hell I live in a pretty damn conservative part of the world, but when my kids (all boys) were going to school they were lorded over by a all female staff. From teacher to principal it was all female. There was one male coach, but he weirded me out and was probably hired by the female principal. I'm pretty sure he likes prepubescent penis. Kids didn't stay there long.
Well ok, that's fine and dandy when they're young, but as they get older they're going to develop increasingly independent personalities and start saying "fuck dad" way more often, and there will perennially be an entire army of creeps willing to whisper sweet nothings in their ears, telling them they're right and you suck in order to lure them away. What will you do, kick em' out? First of all parents rarely actually follow through on that, second of all those creeps will be overjoyed to give them a place to live.
They're home schooled, who are their friends? How are you finding social activities for them to be involved in where they're making healthy connections and learning how to function interpersonally? One of the benefits of schools is stuff like sports and clubs.
Degeneracy is one small part of this, a need for fulfillment and a need for community are some of the bigger ones, meaning you keeping your kids away from school and depriving them of learning how to operate in a harsh social environment is going to just make them feel even more alienated even more willing to fall into whichever cult they first encounter.
Every single parent makes all kinds of declarations about their kids and how nothing is going to go wrong with them right up until those teenage years where they realize they have no idea what they're doing and the ego gets slapped right out of their heads.
