The good man out of the good treasure of his heart brings forth what is good; and the evil man out of the evil treasure brings forth what is evil; for his mouth speaks from that which fills his heart.
He who guards his mouth and his tongue, Guards his soul from troubles.
I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit, for apart from Me you can do nothing.
He who is not with Me is against Me; and he who does not gather with Me scatters.
Do you suppose that I came to grant peace on earth? I tell you, no, but rather division;
“But if your enemy is hungry , feed him , and if he is thirsty , give him a drink ; for in so doing you will heap burning coals on his head .” Do not be overcome by evil, but overcome evil with good.
Romans 12:20-21 NASB
Be consistent. Align your actions, your thoughts, and your words(including your posts) with God's heart. When you speak cutting poison and hatred, that's because hate is filling you up and overflowing. Be filled, and overflowing, only with the Holy Spirit. With compassion. Compassion can lead us to speaking a controversial truth, calling out evil for what it is, for example on the issue of abortion, but let us do it all in God's love and not our own hatred. Not being defiled and overcome by evil.
