Nice to meet you this way triad93!
Thelema encompasses all beliefs, and Thelemites are drawn from all various backgrounds, the only thing they have in common with one another is that each individual is so vastly different and unique. The only thing that constitutes "thelemic belief" is one's own personal convictions for how the divinity of love is naturally mutable under the power of human will.
Most people naturally agree with "harming none", but Thelema doesn't operate under any such guidelines, Thelema doesn't apply boundaries or restrictions to religious ascension, that is what makes it Thelemic.
Thelema, or Thelemic Folk, or Thelemites, they have no agenda designated toward taking from others because the belief is that once a person becomes honest with themselves to find their own True Will in life, or their own personal philosophy that works for them, the whole universe bends in offering to fulfill each persons needs and desires without interfering or harming anyone, naturally.
Sometimes however, if a Thelemite is harmed by the dishonesty of another person, he reserves the right to retaliate by exposing such dishonesty, which may be harmful depending upon the situation.
Thelema is definitely harmful to tyranny. Thelemites, through their Art, tend to liberate the exploited, and work to expose liars, and this of course seems harmful to those invested in "taking from others".
I hope you stick around for a long time triad93!
