Why? Because we have a high percentage of 'sheep' in our population.
When you fall back to the 'sheep' argument, it shows that you really don't care to hear other people's opinions. Why should they care about your opinion then?
Why do people buy Apple products? They're all sheep.
Why do people vote for Obama? They're all sheep.
Why do people believe in global warming? They're all sheep.
Why do people believe in religion? They're all sheep.
Why does the media hate bitcoin? They're all sheep.
There are logical reasons for people to be on both sides of any issue. Equating the other side to 'sheep' means you are unable to step in their shoes and understand the real reasons. You'll never get people to understand YOUR side until YOU understand THEIR side.
Bitcoin is NOT all amazing and awesome. Yes, there are parts of it that are if you have a certain point of view, and I LOVE certain things about bitcoin. There are also really scary parts too, all depending on your point of view.
For example, when I hear someone say, 'bitcoin is awesome because there are no transaction fees', I laugh. It makes NO SENSE AT ALL to love bitcoin for that, at least right now. If I get up in the morning with 1 btc worth $600. I go out an hour later and want to buy something. My 1 btc might be now worth $630 or $570. Really! It's gone up or down 5%! As a consumer, it doesn't really matter at all if I was charged 3% using a credit card, my btc fluctuate so much that I might pay more or less, I don't know. Once btc are more of a stable currency, THEN AND ONLY THEN I will be interested in the 'no transaction fee' thing.
