If I were you (since you're self-admittingly ignorant of knowing what makes a person heretical) would be really really careful from here on out.
Why do I say this? Due to the fact you assure those who believe in both a false Christ and a false gospel that they are in fact true believing Christians, which is against Scripture. Note John 8:24 and Galatians 1:8-10 respectively.
You will stand before God for your assuring them with their false beliefs and false Christs that they are true Christians.
"We" on the other hand will continue to warn them and refute their teachings, and yours, Jude 1:3 as it is biblical to do so.
You really need to sit back and consider what you're doing in assuring those who hold to a false Christ and false gospel that heaven is their home. There is zero biblical teachings that backs you up in said endeavor. You are on very very dangerous ground, sir.
I'd recommend you do some reading up, especially on Scripture, and perhaps
Walter Martin's Kingdom of the Cults. I also recommend you listen to a podcast entitled
Cultish. There you will hear testimonies of those who came out of Cults you protect as true "denominations" on how they were deceived and knew if they died with those beliefs, they were not true believers and would end up in hell.
Read very carefully John 8:24.
