Are all people who answer anonymously that stupid?

So I asked a question here about one particular word in a show. I didn't get the word. So I asked a question, wrote the name of the show, that season, the episode, I wrote the CURRENT time when the word was pronounced - on what minute and second, I put the link on the online free service with that episode... So if you wanna answer, just click the link, find the right spot and listen to one small word to figure it out... Do you know how one genius helped me to find an answer? He answered - "I don't spend 5 minutes to hear your one word..." You serious? I put the link AND the right time to find one word! Can people really be THAT stupid or they just enjoy mocking others? I'm just so frustrated and furious! I think that for this kind of attitude on social media, people should be tracked and charged for the web-mockery... Plus, he gave it as an anonymous. So I wanna ask... when people give anonymous answers, just like this one, do they just hide their names for being stupid, or do they just mock others to get an extra point? I just don't get it, if you don't know the answer to the question, don't give an answer, don't write! What's your problem?! I'm so furious! AGH!
