Please get a reading comprehension class or look up a video about understanding English or something. If I were to say “it’s not that big of a deal lol” then that would be me directly talking about and giving opinions on the subject, so it would show that I care about said subject (in this case your cat image being used without consent).

But since I only said that I didn’t care about the subject that doesn’t apply as I did not mention the subject beyond how I don’t care about it, if this was not the case then the phrase “I don’t care” would be useless and become irrelevant over time.

And while you probably set aside your reading abilities intentionally to make a funny comeback that all the redditors will see and press the up arrow on, and while I do admit I also enjoy seeing a lot of numbers next to that arrow, an unoriginal joke that hardly makes sense unless you drop your reading comprehension to that of a 7 year old isn’t deserving of the orange pixels representing a large value.

TLDR: the only thing I care about is your lack of reading comprehension and/or use of overused unfunny nonsensical comebacks.
