Ah don't get nervous cause of nothing, people usually hate something they don't understand, or if they are afraid from it. Either way if someone is not open minded don't bother about that person, time will explain everything to them, and one day they will realize how wrong they were.
I didn't meet person that hate bitcoins, except couple altcoin lovers that constantly talk how btc will disappear, and how will some other alt coin take bitcoin place, usually their alt coin, but I don't give a penny for their talks.
Lol, it's absolutely right that some altcoin lovers or developers maybe are always talking about bitcoin for bad or cursing it while they know nothing would happen to it and if something happens to it their coin would also not survive.
