There's a big difference between victim blaming and risk avoidance.
No victim is to blame if a crime happens to them.
However avoiding risk is a valid thing to do. We do it all the time. However, it's not an easy thing to do sometimes, and it depends on the situation. Getting into a shower with someone who is drunk is not necessarily a bad decision. Drunk people come in lots of different types, so assuming that all drunk people will try to take advantage of you in a shower is not really accurate.
