None of these things seem like problems that need to be corrected (within reason [1]). Part of being a member of a minority group is that members of the majority group will never speak or behave in exactly the way you would like. That's the nature of living in a heterogeneous society.

There will never be equal proportions of gender, race, religion, sexual orientation or culture in any group. In the interest of everyone being able to work together effectively, we all have a responsibility to draw a line between preference and abuse. People who become abusive should obviously be castigated or removed for the good of everyone. But if we place too much emphasis on appeasing the preferences of every group or individual, we'll be too busy focusing on choosing just the right word in every situation to get things done. Effective communication is hard enough as it is. Parsing every word because it might potentially offend someone only makes the problem worse. Everyone has a cross to bear and no one will ever feel that they fit in perfectly. Some times toes get stepped on, and that's ok.

I think the term "unintentionally sexist" says it all. There was a time when open and aggressive *-ism was common, but that kind of thing is generally no longer acceptable in polite or professional society. It seems like the best thing for all of us would be to focus on what we have and common and what we can do to get along, instead of publishing lists of "I hate it when group X says thing Y".

[1] clearly numbers 6, 9 and 10 on this list are right out. there are several others that might not be acceptable depending on the context/wording
