Okay, we all know that this discussion is going to end with folk still having different views, and that is fine. But as I've said before, please recognise when your point has been made and it's time to agree to disagree.
It's perfectly okay to just stop, or talk about something else, rather than replying to people you disagree with once it's clear you're just going round in circles. After all, not everyone can have the last word so if all parties keep trying to then we just go round and round and round. Please consider being the bigger person and just letting things slide .
Oh, and I am purposely not directing this to one individual, and I'll let folk decide themselves whether or not it could reasonably apply to them.
