You can construct a lot of scenarios out of this though.

Have you not been at a bar and night club before and somebody start acting out, maybe pushing you? 9 out of 10 times you can walk away and nothing happens.

When you start pushing back you can be you start firing up the guy how had too much to drink. I have seen this enough how fights start over nothing because each party just keep escalating the situation instead of backing down.

I think it is wrong to assume that in every situation where you are challenged you have to stand your ground. Not every situation is a like being the new guy in a Maximum security prison in the US.
