The term meltdown - does it cause offence?

I’ve been told that the term meltdown ought not to be used because it’s offensive and the term sensory overload should be used instead.

To my mind sensory overload and meltdowns are two different things. I have suffered sensory overload today but I didn't have a meltdown, I left the overstimulating environment for a quieter environment to recover. I do believe though that prolonged sensory overload will usually result in a meltdown.

I don't think this is coming from the autistic population, I could however imagine parents saying it.

I do find it offensive when neurotypicals use it to describe being angry/upset/frustrated because it diminishes its meaning to what we experience as a meltdown.

What do you think?
