I didn't mock anybody. I simply pointed out how logically flawed claims that Switch will sell the same or less than 3DS are.

I don't take offense in it. But it is a totally condescending way of talking about people. It really is similar to call them dumb.

There is a big gap between saying something is wrong or doesn't seem likely to being "absolutely baffled that there are still people", which basically is inferring their are dumb for thinking like that.

And saying a group of people doesn't make rational sense is akin to also saying they are dumb, just on a little more polite way.

If an argument lacks logical merit, that argument will be naturally be challenged and criticized. I didn't call anybody "dumb", I merely pointed out that a particular position is currently in contradiction to almost all of the available evidence, and hence voiced my confusion that so many would still hold such a position. Why they chose to do so is not for me to say, you'd have to ask them.

You don't need or have to say a point is illogical or that it lacks logic, as you also don't need to attack person but points.

Pointing what contradicts a point is enough, no need to classify the point of someone else. And again it wasn't only saying it lacked logic but then putting how you are baffled that someone would think like that. You may not admit it, but it sounds very condescending.

Well as long as the person accept that is what he is doing then I have no issue.

If you find me condescending, fair enough; you are entitled to that opinion.

But if an argument is logically deficient, I'm going to point it out as such. Arguments are not a protected species exempt from criticism.

Attacking an argument is totally fine, and you do that with another argument and data, without any need to classify the argument because that doesn't have any value in the end.

It is equivalent to me saying your argument is dumb thus you are wrong. That doesn't prove anything, while your reasoning of why the argument was wrong were much better.

Consider what you want. I didn't said he was dumb nor that his argument was illogical, I countered with why the argument was wrong and said that if same line was followed analyzing PS4 then it would have to sell to much.

And there is also a difference between discussing with one user that a sales projection is wrong on the basis used (X1 would sell 70M solely on merit of GTA 6 launching for it, and 80+M if it also had a good reveal) than saying all projections for the future that are bellow 80M are so wrong that you are utmostly baffled. One is analyzing the past and making a very objectively wrong assumption (60% increase in sales due to a single game launch, when the predecessor game already launched on it even if crossgen) while the other is generalizing and ignoring any point made by different people of why they think the console would sell 80 instead of 100M.

Also I have nothing against mocking people, I would even encourage (not here because it is against the rules, and discussion also doesn't involve mockery), but the person doing it must acknowledge he is doing.

Lower hardware sales than I expected.
Guess they overshipped in past quarters. Still, very good numbers and my favorite console.

If an argument is illogical, then I will point out that it is illogical, and use evidence and examples to demonstrate why it is illogical, which is exactly what I did.

If you have a problem with that, then, sorry to come off as rude, but that's your problem, not mine.
