But you did, and it makes me sad to see the testosterone blaming stuff here.
To be honest, I do remember online communities being much nicer back then (we're talking 14 years ago here) but things have changed a lot. I feel like strong moderation and guidelines work great (see HN where discussions are mostly civilized) instead of blaming half of the world population from an individual observation which can quickly be debunked by visiting any female-only forum or subreddit in 2020 for example.
It feels like you're changing what they said into something that is obviously false. It isn't so black and white as "do you believe hormones don't affect feelings", so asking that dumbs down the conversation and detracts from the point that testosterone may not be the only thing affecting online conversations.
I guess it's similar to replying to you with the question: "do you believe testosterone is the sole cause for unkind behaviour online?" That just isn't what you meant.
