We don't need the Laugh reaction.
I've now only had it had used mockingly.
Specifically for example, in a thread where the op is upset about something and I gave a supportive message. Some loser gave me the Laugh emoji because they think op is being ridiculous and by extension, so am I for showing sympathy.
Mumsnet, please just get rid of it. If someone says a funny joke, the clap hands or thumbs up is perfectly adequate. The Laugh emoji is the only one that can be used in a mocking way
Edit to add Please!
