I wasn't having a dig at you - your post was bang-on the money.
I just find it hard to believe that no-one has mentioned the security aspect already. Far too many have slipped back in to the EU and elsewhere from training camps and/or having seen action fighting for ISIS/AQ or whomever, and there are clear, direct lines to those who carry out the terrorist attacks. We're currently struggling to manage that as it is, and every attack brings fresh criticism that we're failing to stop these terrorists moving about, so to relax our [already lax] frontier controls and systems of checks etc would be a step in the wrong direction.
Don't get me wrong, I pity the poor souls genuinely fleeing conflict and its never nice to read, hear or see of anyone perishing in such circumstances - let alone young children. But there are factors at play here that most people don't consider, or choose to gloss over and think it'll be alright.
