Okay. First of all, don't sweat it too much. It happens from time to time and some users are quicker to use block than others. Some use it liberally, while others rarely use it, if ever. Me personally, I only use it on overt, unashamed trolls (of which we get pretty much none of).
Second, kantos and keifermiller both jumped in and commented in the time it took me to hunt down a single video. If anything, that should illustrate this place is pretty inviting, so don't let a single negative experience discourage you. If it helps, I personally think some of your comments are well thought out and I'm interested to see what you have to say down the road.
Lastly, watch that video up there real when you're done reading this post. It's a pretty good metaphor for what you're experiencing right now. You're like that warthog. You're in a new environment, and not only are you getting used to your surroundings, you're also getting to know the residents and they're getting to know you. Know why it's such a great metaphor for this place? Because that Savannah exhibit is full of different animals and here, with the exception of a few common traits, we're actually really diverse. We have people from different countries, different classes, different ages, and different education levels all mixing it up. Even with such a small site where we know each other relatively well, with such a diverse user base sometimes signals get crossed. It's normal.
