I’m pretty sure that he was being sarcastic...
You’re still far too new to understand who is sarcastic, without the usual “/s” and who is not.
Don't worry about having to point out the obvious to certain people. Always remember: There are some on FR that just go around and yell nastily at everyone. Sometimes they leave in a huff but dang if they don't always seem to come back like a bad penny. :)
