Dilemma/family disagreement politically/spiritually?

Here's the issue: I sent out to many friends and family last week, a political editorial with a Christian slant to it. The editorial was regarding the state of our nation's economy and war and other problems. I would say it was conservative. Now I get an email from my husband's brother who takes me to task for sending it to them, He disagrees politically and religiously with the email I sent, and tells me he feels 'chagrin' over the email, requests I send no more such stuff, and tells me we all need to learn to disagree without being disagreeable. Now, I barely know this brother in law, except I know he is very liberal, and not religious. How am I being 'disagreeable'? Now, does it sound to you as if he, or as if I, am the instigator of the beginnings of a family rift ??? I would never start a rift, and my motives in sending that article were only to inform the recipients of the state of our union, from a conservative viewpoint. Was I wrong in sending it to him? Is he wrong to take offense in this way? Could he have simply asked me to send no more of this stuff, and not belittle me like he did? Am I being too sensitive? My motives were to educate only. Another issue - when someone likes that refuses to consider the other side of a political scenario, aren't they being like the stork who buries his head in the sand? Your honest opinions?
