What you're advocating for is the ability to bury your head in the sand and essentially never learn anything from opposing viewpoints. An example... OZK has made several posts in the past that have made me cringe, and some that have made me straight up nauseous. Recently, I challenged something he said in a thread, and he PMd me to respond personally. This resulted in a pretty decent conversation. I see him in a different light now. Had I put him on ignore the first time his posts upset me, the conversation never would have taken place, and nothing would have been accomplished. In a place that is specifically intended for discussion, the ignore feature is detrimental. Like Ender (and others) said.... an ignore feature makes sense for a place like Facebook, but not at all for a discussion forum.
