Not a word would have ever been muttered by me if one on here hadn't bragged 
about being rich and retiring in their 30's to get a dig at me. To top that, 
they then said I was being sarcastic, and I guess socially ignorant.


"sarcasm is a sign of social ignorance, i dont think they have a pill for"


"well i tend to use the best i can , i dont quibble over a few bucks , or pinch 
pennys, mabey thats why i retired at 32, why settle for average when u can use 
the best"

All this over me asking one simple question;

"What I'm wondering is why one would need a tape rated at 130 C (266 F)?
The core should not get no where near that hot, maybe just warm to the
touch which would be around 100-110 F (37.7-43.3C)".

Now the admin here swore to stop this kind of stuff, and has said some things 
to a few others plus myself over nothing close to this. However, just like I 
mentioned, not one thing was done about it. I'm definately not ashamed of being 
on the lower end of the middle class, but I sure don't like rich folks rubbing 
their money in my face. If you notice, I never really replied to this until 
now. The thing is, if another tape will work that is cheaper, there's no need 
for anyone, no matter how wealthy or poor they are to pay extra for something 
they don't really need. That was the point I was trying to get across but was 
called names and made to look bad over nothing. The whole post I originally 
wrote had not one sarcastic word in it, just some reasonable questions. Not one 
other member of this list replied the way this one did.
