Christian is doing what he can. It is clear from this thread that the situation differs among different people and areas. Bringing attention to it in order to encourage people to respect women who choose to be involved in agriculture in any way is probably the most influential thing that anyone can do, and that is what Christian is doing. We tend to speak from our own experience and the views that have been in society, so changing those, where they need to be changed, via encouraging everyone in agriculture to give women the appropriate respect is the best way to improve the situation.
Respect seems to be the main theme and need: respect for women in agriculture as well as respect when others state that they have seen women disrespected in ways that each participant to this forum may not have experienced.
In my area there have not been a lot of women fully engaged in farming, but in my experience those that were out there working hard in the fields and elsewhere (e.g., my mother and my sister used to mow hay in the barns) commanded respect and appreciation. I think that is what Christian is asking for. I think we need to applaud him for standing up for his wife, for trying to change perceptions in any way that he can, and encouraging us all in the appropriate direction.
It seems to me all of the discussion about "lesser abilities," if someone feels that way, should add to our respect instead of detract from it.
This thread has made me realize that while I have seen people really appreciate women working on the farm, recognizing women for farm management skills is something that I have not really observed, and is an area that Christian particularly brings up.
Good on you, Christian! I hope that you do not let criticism, no matter how misplaced I feel it is, to detract you from your cause. I think it only shows that there is work to be done in this area, so I hope that it motivates you all the more.
And, more importantly, that your wife and all other women in agriculture will be all the more encouraged, either by support, or else by an "I guess I will just have to show them..." attitude.
