lets just end this right here man, unless you can bring up something new.

I guess we can agree to disagree xD

I'm not actually sure if you have been contradicting yourself as much as I think you have because in any of the cases you havent really explained what you specifically meant or why it wasnt a contradiction when you said some of these things, so I just assumed you were contradicting yourself.

Assuming things isnt a retarded action by default, it depends on what you assume really, assumptions are videly used in mathematical and philosophical logic, and you'd be amazed if you knew how accurate some assumptions that even seem to "come out of nowhere" actually can be. but yes I agree some assuptions are retarded like for instance assuming something is wrong because its poorly argued (another logical fallacy)

Don't feel too bad about the contradictions anyway, I used to do it a bit back in the day when I was more retarded, and every single time I would notice it or someone else would point it out I would feel like a stupid fuck for probably 24+ hours. I would always try to learn from the situation, I would think about what I actually meant to say etc. it definitely comes down to nurture and not nature, so thats good. With a poor upbringing no real education and no "training" anyone can really contradict themselves, not sure if any of this is the case for you but I wouldnt be surprised.
