But other people might make similar incorrect comments, better that your comment with the reply that makes a correction float to the top (for people who sort by upvotes). The best solution is probably editing if you have the time and upvoting the reply. Similarly I'll upvote something incorrect if I reply to it but downvote if I don't have the time to reply.

This reminds me of the graphs from Brass Eye.

I wish people would be willing to put off eating all meat until we have lab grown stuff, like how most people are willing to put off eating human meat until we have lab grown stuff.
