All this reminds me of the situation between the UK and the IRA in the early 90s. The remotest suggestion that we should actually be talking to them would be met by accusations of nigh-treason and "pandering to terrorists".
Meanwhile, behind the scenes, all kinds of secret negotiations were going on and here we are 15 years later with a lasting peace.
All this BS about not talking to the "enemy" just leads to deeper and deeper entrenched positions. Someone sticking their nose out of the top of their trench and saying hi should be lauded, not villified. Idiots.
