POLL: should people be able to downvote?

Sure, I get the point of downvoting stuff such as people who are toxic requesting an unban, or people cussing out league/riot, but so many well made posts never get seen because they are downvoted. I used to have the habit where if a post had negative votes i'd downvoted it and keep scrolling, not even looking at the text inside. I've stopped doing that of course but it still feels like people do that.
