I guess if you get downvote for saying something ironical, then that's the loss of audience, not you.

One can argue that a thoughtful irony which gets downvoted might be more interesting than thoughtful irony which gets upvoted because of the points you mention.

Irony shouldn't be in a bubble of all upvotes. Funnily enough I had searched up some irony quote websites a few days back and going back on them was fun to find a relevant quote:

Irony is just the honesty with the volume cracked up

- George Saunders.
