When you see an informative meme, or someone saying something you don't know to be true....if you then ask for a source without first having tried to find one yourself, you're still a sheep.
If you tried and failed, ask for a source.
If you didn't try at all and ask for a source, you're a sheep. Plain and simple. You're still forming your own mind by the work of another. This weakens you.
Don't beg for sauce like a sheep; hunt down that sauce yourself like a LION.
Asking someone else to do something that you could easily do yourself is a sure sign of being a fag/sheep.
Having said that, if you’re bringing new information the the group you should include a source. Not only will it enhance the credibility of your post, but it will save everyone a lot of time.
