You want other people to deal with the things you don't like and filter stuff for you, to improve your own experience and shield you from the filthy masses. God beware you have to endure a comment you don't like, your royal highness.
I'd rather see you gone than the people you complain about.
Filtering is a valid form of improving signals. If there there was a reliable heuristic for users posting low effort content that was better then the user would be considering that instead.
If someone in a chatroom for example is being spammy with their messages at the expense of noticing posts one finds more relevant then blocking them isn't due to considering them some filthy pleb but improving their experience. If the user being filtered never becomes aware there's no reason to be offended, either.
Edit: also I wasn't the one to downvote you if that makes any difference.
Core function of HN Front page is based on "other people filtering stuff for others". Filtering out by any criteria (karma, account color, first letter of the nickname, whatever) doesn't automatically mean that someone is a jerk as you have stated in the comments nearby. It just means that someone is selecting the information to consume and does not harm anyone (perhaps besides the selective person who might miss interesting info due to selection).
