[QUOTE="snakeraper11b, post: 13061617, member: 128473"] I'm not taking it personally, I just hate when some people get so fixated on something they are not willing to open their minds to new ideas. If you're so progressive in your ideas and developments as you say, I feel like you would be willing to lay down your defenses and actually explore the ideas of others.
