>The major objection is that its predictions are for things at a microscopic scale that we cannot yet test Yet? That's generous. String theory (whichever one you choose) works on the Planck scale regime, around 15 orders of magnitude beyond what the LHC can reach. Just scaling the LHC size you'd need... 27km(10^16TeV/14TeV) ≈ 2.710^13 km ≈ 2.4 ly Sure technology doesn't scale linearly but come on, string theory testing scale is impossible.
