Yeah, known lots of liberals and progressives in my day, including hard core socialists and communists. Never met a one who was anything but horrified by pedophilia. Claiming that liberals and gays are pro pedophia has been a long time strawman argument on the rights, as is this OP's post. Hateful twaddle as opposed to the stupid twaddle so often flowing from the right. Anyone who thinks they are on "the right side of history" usually isn't, reality is complicated and seldom one sided.

@Matias
There is no right or wrong side. There's just whatever happened.
Homo sapiens is a conflicted species. There is no way around that. You pull for progress, or you pull for going back to a time that never really existed, or you muddle through unawares.

You don’t get to say what I believe - that’s my job .

I don’t believe in right and wrong from any ultimate or absolute perspective, so, from my perspective, there could be no “right” side of history.

What I believe in is biology.

Humans developed enough brain autonomy that they could make decisions and take actions that might not be in sync with what nature had otherwise selected.

So we went down this path of domestication. It’s not objectively right or wrong - it’s just what happened. There’s also no objective “progress”. Progress is a word humans made up to describe this process of domestication. Then as a backformation, we started calling progress “good” or “right”.

But whatever we call it, and however we value it, change over time does happen - it does “progress” (verb).

Some people are uncomfortable with change. We call them conservative. Some people like change. The English dictionaries that I have access to call them liberal.

Humans tend to be tribal. They think their tribe is right and all other tribes are wrong. But biology has a different idea. Biology makes different tribes because a population that consists of various tribes has more reproductive fitness than a monotribal population.

This is to say that conservatism and liberalism are genetically distributed in human populations in a way that balances change and stability.

It is the giraffe’s job to carry out giraffe duties. It is the squirrel’s job to carry out squirrel duties. It is the conservative’s job to carry out conservative duties. And it is the progressive’s job to continue exploring the human potential for domestication at whatever pace the conservatives can tolerate.

There was a time in our distant past when our ancestors were no more domesticated than any other wild animal. From that time to this we have become progressively more domesticated. That is a biological and historical fact. No one can determine whether that fact is on the right or wrong side of history - it’s just what happened.

Progress is not just technological. Progress is how far we have tamed ourselves. It is how wide we have made the artificial gap between human and animal. It is the degree to which we can establish and sustain moral abstractions such as equality, fairness, justice, and compassion.

That is what I believe.

@Matias
No human is free from the influence of tribal identity. And we judge other tribes by their worst examples, and our own tribe by its best examples. In reality we are all Homo sapiens being Homo sapiens. We all experience our own worldview as the correct one, and others that differ as “confused”. Every individual has a unique view. We can share them. None are complete or without error. They are perspectives. The popular meanings of words migrate across cultures and across time.
