The “ignore” feature works as you have described as skipping posts. The post is still there, numbered in sequence, but the program does not display text of the post. You have the option of viewing it or removing the name you have on ignore from the ignore list. It can make some threads a little difficult to follow but you can usually get the gist of things. I’ve just found that many of these controversies are endless and life is too short to tediously repeat same thing over and over to the same posters, many of whom appear to be rather single-minded in their approach as well as highly resistant to any opinion other than their own. I have been accused of being “afraid” of such posters, but that’s not the case at all. I am not afraid, I am merely unwilling to spend any time or resources on endless, pointless argument and yet that appears to be the only thing that some posters are interested in. As a result, after a while, most end up on my “ignore” list.
In addition, as you have no doubt noted, disagreement with the doctrines of the Mormon faith will often elicit hostility from its adherents, those who are either unable or unwilling to distinguish disagreement about doctrine from intolerance of people. Such persons often fall into the “single-minded in their approach as well as highly resistant to any opinion other than their own” category, so “discussion” with such persons is often an exercise in futility.
That quote of Fr. Rutler’s in my signature has many applications both within this forum as well as outside of it. For example, it has a very definite application to politics.

… And yet is is often just as pointless to have a discussion about a political issue with such persons as it is to have a discussion about religious doctrine with some posters to this forum. Many people who are uninformed, yet highly opinionated, about a political issue will cling tenaciously to that opinion regardless of the facts. It can be rather frustrating to try to discuss anything with them…
…the tendency of some people & groups to shout down those with whom they disagree. Lacking information & a sound basis for dialog, they instead resort to noise and sometimes violence to drown out/marginalize the opposition. Unfortunately we can see examples of such behavior on TV on a regular basis. .
