>for posting well-written, thought-out responses which other people disagreed with
I could write a well-written, thought-out argument in favor of segregating blacks. I'm not suspicious of you - I'm just saying, maybe you're making too much assumption about how valuable your writing is, since you've only used "well written" and "thought out" as evidence.
>just for playing Devil's Advocate
Do you announce that that's what you're doing? Do you think there is such thing as a comment that deserves downvotes, but that wouldn't if it was written the same word for word with the exception of being announced as a thought exercise? (Not rhetorical - I suspect my personal answer is yes).
>within a minute
A minute is a long time.
> They are coddled and react negatively to things they disagree with
This is a broad and specific accusation to level at people just because they downvoted you. It's also a very convenient way to convince oneself that one is "the better person".
