I rarely use lower-case in memes. Only for effect... to highlight a word.
And I don't judge case. I do, however, cringe when I see grammar issues. Not so much at spelling, because some people are using phones with auto correct. But I DO try to proofread my output before posting anything. Sometimes I still fail... but I try.
Btw, I hadn't noticed anything wrong with your use of the alphabet.
And.. I won't go back and check!
