You're being 'insulted' because you're coming in here and acting like you own the place. This is considered bad form *ANYWHERE* on the net, much less in a long-established community such as this.
You'll find when you come into communities like this that bonds (whether loving or hateful or otherwise) will have long since been established, so it's like moving into a block in a new neighborhood where everyone else has been neighbors for 25 years: You can either act in such a way where you endear yourself to the community and they pull you into their group, or you can act in such a way where you offend and alienate the community.
You did the latter. Is it any shock that the community reacted to you w/ sarcasm and suspicion? And it's not like they're out to specifically get YOU or something. This is standard operating procedure for trolls and your behavior doesn't distinguish you from them.
Be a little more respectful towards those you try to have conversations w/ (like, for instance, cut the 'you're insulting me, wah, wah' bullshit and just put your opinions out there.
And be prepared for people to shoot you down and to back yourself up. It's an adult discussion forum not a freakin' playdate. When someone challenges what you say, just back up your opinion w/ examples. If your opinion is inane or thoughtless, expect it to get shot down.
A lot of people don't abide by what they find to be bullshit here. If that doesn't appeal to you, maybe you should look elsewhere for your 'Stros discussion.
If it does, then just discuss and don't make having your opinion shot down personal because then you REALLY won't enjoy the experience.
