This is the most important issue of our generation. You cannot have it both ways Mr. President. There is no middle ground. You either support the right to privacy or you do not. There are only two options and you have to pick one.
CALL your representatives to let them know how you feel and why. Email them. It works, they do listen. There are bills being proposed in NY and CA that would force companies to insert back doors or face a penalty. The issue is now political at the highest level, and our President is spreading the misinformed view of fear, uncertainty and doubt. Given Trump's campaign success, we should all be very afraid at the effectiveness of this uninformed stance.
The argument is that if you support the right to keep your document private from everything except legitimate government access, you can't insist that manufacturers build in back doors to allow government access. There just isn't a technologically feasible way to build a backdoor that only government agencies with warrants can use.
