There's no need to apologise Matt, I admire your optimism on this forum. In times where some may feel low or cynical it's refreshing to have a positive outlook.
As others have said people will have different opinions and that's the joy of a debate, you can disagree but laugh about it five minutes later. It doesn't have to be heated. Theme parks are an interest of mine but outside of that I have a huge interest in music. Me and my best mates have disagreements all the time about which band is better, etc. It can feel like a personal attack especially when it's something you're passionate about. But we're still best mates by the end of it, nothing changes there. Discussion is good for others perspectives.
Just try to steer the conversation away or perhaps just leave it if you feel it's gone too personal or it's getting you down, that'd be my advice. Keep up your posts Matt, you seem like a good guy that has a huge passion for theme parks. Positivity definitely isn't a bad thing to have!
