In all fairness mate, I’ve read the posts & you’ve interpreted them completely different to the way I have. I don’t think anyone implied you were being untruthful which you have somehow interpreted ‘tbf it’s a forum’ as meaning. I can’t fathom why you think that implies you’re lying?
It’s easy to have a barny with someone online just by misinterpreting a post & whilst everyone seems to agree GDM is a condescending, patronising, doubling down ****, ****, ****, ****, ****, I really don’t think he’s the sort of person who would call you a liar for no reason
As a new poster, I’d suggest the best thing to do is try to have a laugh on here & try not to take anyone or anything too seriously or people may go out of their way to wind you up as we all love reading a good rant. Most of us have done it & been there mate :)
