the levels in the autism spectrum indicate the amount of support needed by an autistic person. High functioning autism is basically level 1 so low supports needs, level 2 is substantial supports need and 3 is high supports need. Labels like Aspergers or high-functioning are clinically irrelevant today, as in the DSM-5 all the different types of autism were joined into one single diagnosis, and that is autism spectrum disorder, hence the levels

Probably similar, there are multiple terms that keep getting changed because they are offensive to someone or another... High functioning, low support needs, and presumably level 1 are the same thing. Note: haven't fact checked, for all I know level 1 could be high support needs.

In my experience they are used as a tool for discrimination

cool! it's always nice to remember that you're not an alien and you're not alone and there are people you can relate to

that tape is so heavy it crushed my skull
