free speech can be of any type. Selfish, angry, wrong, silly, disgusting, false. If some hypocritical power-crazed type like you starts to brand some forms of speech as inappropriate - it's not a free spech.

I live in Russia, and know who talks just like you? Mr. Putin. He can trow you in jail for a "selfish speech". I hate it to the bottom of my heart. It's a blessing that you can only do some downvotes to silence your enemies, that you just CAN'T silence people with a violence. Power corrupts. You and ones like you are corrupted by power of your downvotes.

It will be better to not seduce anyone with power to attack fellow humans. Downvotes are cancer just like self proclaimed enforcers, censors, custodians and guardians. If you don't like what other people say - you can argue, you can disagree or enlight. But you want to do harm instead, to use brute force. And by this you confess in having no vaild argumets, all you have is a pointy stick to poke people in submission.
