Lemmy is so far left leaning because a large part of its existence is due to people being mad at capitalism

Thinking like this is why people get surprised when right leaning parties get voted for in elections

Not really. I mean that "because..." part.

Leftism is inherenty tied to technology, especially new. It's part of its lifestyle. EVERY new, massive social "site" (or online service) is expected to be left-leaning by default. It may later change its political viewpoint, but in its relative infancy it's left.

Rightism is more about actions taking place in real-world. As such, the technology isn't perceived as more than a tool, used for specific purpose only, rather than part of, or the foundation of a lifestyle.

...and of course there's a plethora of alternative political views, options and convictions that are a mix of either extremes of the spectrum - if you meet a person online, it shouldn't be surprisied to learn about "pro-life", but also "anti-Trump" and similarly puzzling approaches to various aspects of life.

tl;dr: it's not about bots. It's because Lemmy/Mastodon isn't popular enough to serve as a tool for right-wing politics.

I dont think that is the case. Left leaning people are just much less accepting of authority, so there are more likely to move of of reddit. right leaning people also tend to be more conservative, so they are more likely to stay on there old platforms.

Grandpa also doesn't understand federation

Lemmy is a decentralized protocol not a centralized americanized political leaning social media.

The political discourse seems toned down here, I am already happy with that.

I would say less "left leaning" and more anti-capitalist / anti fascist. More socialism less Nazis.

Not by bots but by rage farming algorithms. Rage farming the right is easy and profitable. Facebook has gotten that down to science. The fake absolutist free speech espoused by Twitter's management as well as the apparent moderation inaction by Facebook are all about that. Letting right wing nuts rage freely generates engagement, generates ad revenue. The only thing the platforms actively manage is making sure that big name ads don't show up on Nazi posts.

Among people in general who actually read comments, the left does have a distinct advantage.

Lemmy also isn't profit driven, so you don't get libertarian tech bros.

For all we know the people that are on the right have gone to other platforms. That doesnt stop you jerks from saying im on the right even though im not. For some reason both sides have adopted a "with us or against us" mentality and everyone is a nazi.

i think its not just the bots but also that the right want their posts to be seen and want to "present" themself and their "opinions". And i think for that, lemmy is just not visible enough, yet.

Imagine if Lemmy just totally avoided playground level political debate?

People will stay where they're right, and avoid places where they're wrong. See: Facebook groups.

I honestly don't think that's the case. There's tons of right leaning and left leaning people that are bots. You can just never know. I think it comes down to the age range using this place and the culture using it. Reactionary people prefer sites like 4chan or the other online communities designed to cater to them. The age comes in because based on research the largest age demographic using Lemmy is between 25 and 35. This site is too underground to attract the middle aged and older cohort that are right wing. It's also not hip enough to attract the under 20 crowd who make up the bulk of Steven Crowder, Ben Shapiro and Tim Pool viewers.
