The Leftist mindset (in all its versions) is the largest inhibitor that we face in this fight against islam and for our country. Leftist mindsets are the facilitators for islam worldwide and a great many other non-sensical social problems. 
Whilst many leftists that we meet sit at different positions to each other along the political spectrum due to variances in their own personal influences/values/degree of brainwashing- it is important to investigate and note the root sources (socialist movements) that work very hard to achieve indoctrination within the masses through many corrupted platforms (such as media, educational institutions, workplaces) and the PC mechanisms with which they achieve it (blatant deceitful journalism, curriculum bias, law-fare such as 18C) 
The fruits of this labour can be seen in the common elements that most Leftists share such as: 

• intense dislike for conservative western governments

• intense dislike for patriotism

• support for globalisation/forced multiculturalism

• undermining of western nations sovereignty

• support for restrictions to free speech

• racist against whites.

• Will apply victim status to minority groups regardless of the facts.

• use of mislabels & made up words to deflect away from their ignorant lack of facts/rationale. 

e.g. "racist" "nazi" "islamophobic" "homophobic" etc..
