I do:

Please critique

You had a good point in your suggestion so I changed my "100% good" statement.

Oops sorry.

You're going against the grain - not a bad thing but it means you're going to have to really lay out your reasons if you want to change the way the wind is blowing. Elaborate, please.

I invite brutal honesty on everything I wrote there.

I intentionally picked examples dated prior to your post. Usually I would not bother to justify myself like this but I've decided that I like you.

Of course there are times when I disagree, also, and will continue to disagree until somebody gets somewhere or the discussion is lost to the sands of time. But I will not continue disagreement I don't see a way to make the disagreement constructive. If I don't think that it's likely for me to get through to a person, I will choose my battles with them.
