What do you do if you encounter a communist

1.  Be very careful of trusting what they are saying.  (Especially Politically)

2.  Be wary of who they are endorsing.  

3.  Call them out and tell them to repent.  Preach the Gospel.

4.  Be careful as far as relationships with them. 

5.  There may be a spiritual element and influence over them.  Be ready for spiritual warfare.

6.  Make others aware of them and their tactics.  They may falsely accuse you.

7.  Look at family history and see who they are connected to.  Bloodlines and relationships.

8.  Not all liberals or left leaning people are communists.  They may be in deception.
