Just because we're unfortunately used to it doesn't make it any more acceptable.
Hate when people don't use the "quote" button when responding to a specific post
But in the event you were following this,
When my response to a post immediately follows said post, and is obviously a response to said post,
I don't feel the need to 'quote' said post.
I am not sure what you find unacceptable about it. Maybe it is just that I am not chassidish and ammissing something. If so, maybe you can help me out with that.
