I watched a few of his videos back in the day.
Basically he's a Molyneux acolyte who wrote a few books that seem to be very edgy. He seems like a wignat at times saying very edgy things. Other times he goes off against wignats and says that enjoying racist cartoons is a sign of being a sociopath. He has "interpretation videos" looking at various things on Youtube. He doesn't seem to like rap music at all, which is a positive. He doesn't enjoy sex, and rails against coomers with a vengeance. He has a farm and enjoys line dancing and simple Christian morality. He goes on rants on Telegram that sound like the babbling of a homeless schizophrenic. He offers people personal self-improvement advice from the school of Stephen Molyneux and family relationship psychology. He seems like at any point he could snap and chop you up into little pieces while laughing at the top of his lungs. He was in a folk rock band with stoners that appears to have been pretty decent, and physically looks to be your typical California hippy but is actually a based and redpilled fascist with an appreciation for self-discovery. Groypers treat Franssen with a deep reverence and call him "Father Franssen" the wise elder of the movement. Franssen babbles incoherent mysteries about cryptocurrency and asexuality and smelts the golden ore of America First's radical vanguard political theory. He's ripped and jacked and looks like a gay firefighter, which appeals to groypers who enjoy watching him chop wood on the farm.
TLDR: he's the wise gay autistic cowboy of the movement.
