Indicating sarcasm ruins the sarcasm

Sadly, it is missed on a lot of people. Without the disclaimer, I would then have a bunch of serious replies “educating” me about my life choices.

Squint or pretend it’s not there. This crowd is hit or miss on picking it up o’ naturál.

If you don't make it clear people will think you're serious.

Sarcasm doesn't work online, If I write something like "Donald Trump is the best president ever" you don't have any way of knowing whether I'm being sarcastic or I'm just really really stupid. Only people who know me can make that judgement, and basically nobody on here knows me. So I either have to avoid sarcasm or make it clear that I'm being sarcastic.
