So...you call people Marxist, pot, anal, and unable to drink in God's word, but are frustrated by the lack of unity?
Well, is that better than calling them Satan, as Jesus did?
But to address your accusation point by point:
Projection is what tulipists employ and it is a Marxist tactic, and stating truth is unifying.
Pot refers to the proverbial "the pot calling the kettle black", which is what you did, so it is a true/unifying reproof.
Anal was in the category of "if the shoe fits", so if it doesn't fit, I apologize for reproving wrongly.
Ditto with the reference to the proverbial "you can lead a horse to water...".
Can we exercise reproof rightly?
Yes, but it is not always simple or well-received.
