I like you, Ed, but these are my honest thoughts:
They are not pounding these events down anyone's throat, and likely no one outside their area would know about them if not for this thread. They are promoting nothing, just holding a couple events that have a humorous theme that fits with their local flavor and taste. Anyone who disagrees is free to NOT attend.
All areas have their preferences, why bother this gang with something they're having fun with? Must all cache pages be sober, epic, dramas? Expressing a dislike with satire is not a political agenda. There is nothing to hide, they don't like lame micros and poke fun at them. Not a scary conspiracy, in my opinion. Why must there always be a smoking man?
The tone and word choice here make your feelings clear. Why join their forum and read their anti-micro rhetoric if it offends you? THEY are not making a loud deal of this, but I question why you choose to do just that? Remember, you WENT to their forum and SEARCHED out their caches, not vice versa.
Their disdain is for lame micros, not "others," there is a big difference. Why on earth would it matter to the rest of the caching community that there is a group of cachers who dislike micros? We're grownups, we can handle it. There are cachers who hate many things, what difference does it make? At the end of the day, absolutely none.
TRIGO is well-known for their feelings on this. I seriously question your motives in joining their regional forum. Are you absolutely certain they will ruin your next micro-caching vacation in Pittsburgh, or did I miss the thread where they were plotting to take over Alabama?
