I'm agnostic to a "block" feature.
That being said, it still blows my mind that some self-professed adult professional pilots who fly big jets and are spoiling for a fight with the Company are also afraid to participate on a message board because, what, somebody might be mean to them on the internet? IGNORE THEM!
Work-related posts don't frequently get turned political. If you have questions ask them, if they don't get an answer bump the thread because sometimes stuff gets missed by people who actually might know an answer. Of course, direct communication with IPA staff and/or committtees is the best way to get accurate information from SMEs.
Moderators are line pilots and have lives outside of work, so sometimes things take a bit to move around to the most appropriate place. If you have heartburn about a particular thread, ping the EB about it...I doubt people are monitoring looking for a single post saying "Politics?".
My experience is keyboard commandos don't interact as adversarial in the real world...but their electron reputation preceeds them on the line, and impressions can be difficult to overcome. Going back to my comment about self-professed professional pilots, it is striking that more people don't follow "The Golden Rule"...but hey, that's both a human and pilot trait I've seen across multiple segments of the industry. We IPA members are not enemies but colleagues for goodness sakes, so let's pull on the rope together even if we disagree on a given topic.
Oh and retirement...raise both the DB and DC to maintain diversified retirement income, and if we can get a tax-advantaged vehicle for spill/CoC that'd be swell.
