I'm not assuming the worst - My post is based upon the anecdotal evidence of the behavior of people in game threads when attempting to play a game that has content they wish not to see. What I am saying is - just ignore the tags of content not wanting to be seen - avoidable or not - there are THOUSANDS of options of games still to choose from.
Also, more likely - than not - that question has already been asked by someone else previously (unless it's a relatively new game), just search the thread for the word avoidable.
Save time, save headaches, save looking like an ass by asking in a thread "is <whatever> avoidable" and just move on to a different option.
In the end - to paraphrase Frankenfurter scolding of Janet in reply to her critique of Rocky, "I don't like men with too many muscles" - not every game is made for you (in general - not you specifically).
