Ableism is bad grammar, so "able" is a noun now.

It appears to me that some people on the left don't know how to use the suffix “-ism” to refer to discrimination.  I hate to be pedantic, but “ableism” is a poorly derived term.  “Sexism”, “colourism”, “ageism”, “racism”, etc. are all formed by derivation from a noun.  “Able” is not a noun, according to both of Urban Dictionary and Wiktionary.  According to the OED it can be used as a noun meaning the letter "A".  I would like to point out that it isn't what ableism is supposedly discriminating based on, how disabled someone is, it must be derived from a noun meaning the degree to which someone is disabled, something like disablednessism, or abilityism, or ablenessism, something like that.  Alas, there is no way to correct these things, we can only backform to make them retroactively gramatical when it comes to malderived constructions.

Actually no, in achieving common usage, ableism has neccesarily created a new sense of the word "able", as in "His able is deaf" or "his able is that of having no disablity".  Able can now be used like that because ableism is bad grammer.  But let's not do this again.  I would like to remind that discrimination on the basis of dominant hand is handednessism.  And on the basis of religion is religionism, because this is how the suffix -ism, when refering to discrimination on the basis of ____ works.  It has to come from a noun.
