If emojis are that much of a concern, best not to post.
or, do what makes you happy. You can't control others responses via emoji (EMOJIs !!!!) will be ... if it causes enough distress to create a thread and blast CW and JS, maybe rethink if this is a good place for you. for the OP, enter the cave at your own risk... yet here we are outside of it.
The guy posted a simple thread with a suggestion for something he thinks would make the site a better user experience, and you jumped all in saying he 'blasted' CW/JS & should just not post altogether? Get a grip.. @'ing someone so they actually see your suggestion isn't blasting, dude. & it's clear he's not super upset or anything, just has a suggestion - are those not allowed anymore?
