People will do anything as long as a public figure does it first. In fact, people will do anything regardless of whether or not a public figure does it first. The way I see it, people are generally very stupid and will do anything at any time, purely for attention.
Yes, it does seem people will do anything as long as a public figure does it. Too many people are unable or unwilling to think for themselves and make clear decisions. They look to public figures to tell them what is right and good and often times it is detrimental to themselves and others.
Throughout time people are sheep. For a while, people all ate granola. Now people are on to eating flaxseed. People wore slap bracelets through much of the 1980s. Now they are on to wearing anklets and other silly things. If a public figure sets the trend, people fall in line without thinking about it.
Though it is probably true that some people will go along with public figures mindlessly, there are those who do not feel the need to copy off of others. Some people out there prefer to march to their own beat or even not do something in opposition of that same public figure. It is important to some people to be individuals and unique.
