Okay, so the House of Representatives will vote on House Resolution 888, which supposedly seeks "Affirming the rich spiritual and religious history of our Nation's founding and subsequent history and expressing support for designation of the first week in May as `American Religious History Week' for the appreciation of and education on America's history of religious faith." However, there are all sorts of problems with the resolution. I don't feel comfortable making any assertions about it here, but you can visit the Talk to Action website for details.
Here's what can be done about it, or specifically what I'll be doing:
1. Research. Read the proposed resolution in entirety. Do a little fact checking. If you find the bill is full of lies, then proceed with step 2.
2. Find out how your representative voted on House Resolution 847: Recognizing the importance of Christmas and the Christian faith. You can check here.
3. Write a letter to your representative asking that he vote "nay" on House Resolution 888 . There's a form letter here, though I highly recommend you write your own.
Hopefully, with some effort, this will not pass.
