Using Lemmy requires some modicum of understanding in technology. Most conservatives I've encountered tend to be technology-ignorant at best, and technophobic at worst. You don't see as many differing political views on Lemmy cause some/most conservatives are too inept at technology or can't be bothered to figure it out.
Reddit was just easier to get into, and as much as I personally like Lemmy, it's a hard sell to some from the outset. If the signup could be simplified (which I understand federation and why it can't be that easy), we could see an influx of more outdated viewpoints on the platform.
I also agree with others who have stated that most "conservative" philosophy involves denying rights to those who have only recently (last 50 years or so) been afforded rights equal to their own. I'm also growing increasingly suspicious of how much lead was actually used in the products consumed by boomers and some Gen-x before its use was known and most of it banned or removed from products. It seems too many in their late 40+ are going from normal human being with empathy towards others to RAGING MAGA CONSPIRACIST, seemingly overnight.
