That's why I left Stack Overflow. But people in general have definitely turned up the rudeness.
It's okay to disagree but let's be respectable; just my two cents.
Also, when I first learned coding, I would jump right into 'coding' the solution while my classmate would pull out the pencil and paper and 'design' the solution. It was definitely a hare versus the tortoise moment for me. Each person has to decide what works for them, but I was off to the races and got stuck while the person using pencil and paper had me scratching my head as I observed his approach by beginning with psuedocode. Long story short -- he would have his homework done after the slow start and I was up all night after the fast take-off trying to finish the assignment.
