You're not making an abstract point, you're making a minor and pedantic point. The comment said he didn't remember the exact details. His core idea is true even if he got the details wrong: that whole-industry revenue from movies is much smaller than Disney's overall business. That's an interesting insight. Your comment might be more useful if you acknowledged his core idea even as you corrected the facts. Instead you appear to be in such a rush to prove you're smart that you totally missed the central point. Just sayin.
