Sick of hearing that we can't go too far left

The Republicans have driven us so far to the right that we're stuck in the ditch on the side of the road. Slow and moderate isn't gonna get us back on track. Why is it ok for them to express radical right wing ideas, but on the left we need to keep it reasonable and moderate? If the country wanted reasonable and moderate then Hillary would have beat Trump and we wouldn't be in this mess. People want candidates who inspire and excite them. The real issue is whether the country has drifted right overall. If it has then we're screwed anyway.
