Is it "pushing their belief" for someone to start a thread on the fire?
Interesting question really...depends entirely on the content and how it is presented.
For instance, a thread that wishes seasons greeting and good cheer is inclusive.
A thread that includes "I want to hear my beliefs coming out of your mouth" is proselytizing
That would be true, if you can explain how a posted thread forces another poster to respond in some fashion.
Same way you responded to mine.
You didn't have to.
True. But, I'm not the one that's taking the position that a thread started in support of a belief in a higher power invites argument relative to the veracity of that belief.
