You've all come up with many good ideas and thoughts. This is my DH's older brother and I know how much his interractions mean to him even though it offends him too. He has responded back rather vigorously and I think it adds fuel to the fire. Yes it does.
We are supposed to stay at BIL's company's apartment. This fellow is pres and CEO of the company and it is something that would make big family problems if we don't stay there. There are other family members staying at their home. (6 bedrooms). They gave us the apartment as our sons are also coming in and we would have more room and privacy. So that is essentially the same as staying at a hotel, because you will have your own "space" away from the offensive BIL. I wouldn't do anything to jeopardize the family relationship by not accepting the use of that apartment. The wedding party from out of state are staying at the house. We are expected to participate in all the events, even the rehersal dinner, which I feel is just not necessary. Correct etiquette states that anyone from out of town gets invited to the reharsal dinner. So why you may think it is not necessary, they are being "etiquette-ly" (is that a word???) correct. I guess I honestly have a lot of stress building over this event as I will need to have a lot of new clothes and on top of the wedding expenses it is a bit much. He is a true type A and very successful. He is also very generous and ethusiastic about having the family together. I do want to have a good time and make my neice's day wonderful. Then don't get into it with her father.
I think I will just email him myself and tell him it is hurtful that we have asked him not to forward this stuff and he still does. Some of this stuff is down right nasty and offensive. If it continues I will just not open the emails. DH can do as he pleases. I'd ignore them completely. No response at all. Consider the source, remember & accept that you & he are politically opposite and he has a right to his views and you have a right to ignore his views.
Thanks for all the good advice.
Having a crazy SIL as I do, I can give some pretty good advice on how to handle annoying relatives. You are not going to change him. He is a Type A personality, so he thrives on stress, tension, drama. Type A's get their "high" from that sort of thing. So, you need to develop an attitude of "bemusement" when you deal with him and his differing (from yours) political views. E-mails...glance at them. If they are not wedding-related, smile and think to yourself "Oh, there's that wacky BIL and his crazy ideas aagin" and move on. Conversations...don't get into political discussions with him. If he tries to egg you on, say, with a bit of a sweet, yet condescending, smile "Oh BIL, in the interest of family harmony, you and I aren't going to discuss politics". If he presses, repeat. If he presses, repeat. If he presses, repeat. It also helps if you have another topic that you can bring up to change the subject. Something like "Oh BIL, in the interest of family harmony, you & I aren' going to discuss politics. What a beautiful spot this is for the wedding. How did you guys hear about it?" or "the food is delicious. Who chose the menu?" or "Your daughter looks so beautiful and is such a lovely young woman. You must be so proud" or any one of the myriad number of things one can discuss at a wedding.. .after all, he can't be the only kooky relative you have!
Now I realize that this is easy to say and hard to do. But he is trying to get your goat. If you react, he's won. If you treat him with a sort of resigned amusement with regard to his political beliefs, you'll aggravate him even more, but he'll have no recourse without making himself look bad. He can't "fight" with someone who won't fight.
It took me a long time to figure this out with regard to dealing with my crazy SIL. Trust me, it works.
May I also respectfully point out that it sounds like you may feel a little "less" than him based on your comments about needing lots of new clothes, him being Type A and "very successful" and so forth...perhaps this wedding is a bit more "society" than you are used to, which is causing anxiety???? Just some food for thought....
