No, but then I have always been careful about spelling and grammar. It irritates me greatly, however, to find errors in a post I thought I had proofread!
And I actually don’t see that it is shaming to anyone to make fun in a general way, when no one specific is being called out. I have been made aware of many of my own errors by that sort of general humor.
I actually find it patronizing for people to assume that I am so ignorant or careless that I don’t want to improve my language skills. I participate in a French-speaking forum and greatly appreciate the other members’ attempts to improve my French. They manage to correct me directly without being offensive about it, so it can be done. I am grateful that they think highly enough of me to think it worthwhile to engage with me at that level, as well as at the level of what we are actually discussing.
