I agree: squicks are the line not to cross, and only to toe around the edges of if you are absolutely certain that it will be OK thanks to prior knowledge of the recipient (for example, I hate sexual violence, but if a character was cornered and being molested and turned the tables on their attacker in a violent way, I could well be OK with that because I do love a good bit of well-aimed thumping.)

You are quite right, I shall aim for a great story! That will excuse everything! (Bites fingers in horror that it will now end up being mediocre and show all the flaws. Woe!)
