Your big error here is to assume White Fang is an anti-Fauna faction simply because it 'disrupted' the civil rights demonstration. If they are an extremist pro-Fauna faction, then they may see more peaceful groups as 'traitors' and 'cowards', which would be a motive for them to 'disrupt' the demonstration by sending in masked members carrying weapons and shouting anti-Human slogans.

I also think that connect the Fauna to the Grim is a mistake. They may be symptoms of the same feature of the RWBY world's natural order but even that is unsupported as yet.

My guess is that Weiss (whom you will learn more about in Episode 2) is a neutral, guilty of anything only by association with others who use the snowflake logo. Blake and Adam were clearly attempting to destroy a shipment of something with her symbol on it, indicating that whichever movement they belong to (I suspect t hat they are members of White Fang) opposes those who use that symbol.

The fact that Blake wasn't willing to kill the crew of the train simply because they were carrying a shipment that her group wanted destroyed suggests she thinks before she uses lethal force; she is not a believer in guilt by association. I suspect that she'll give Weiss a certain degree of leeway but that Weiss will have to work very hard to escape the negative association in Blake's mind with those who had stripped the Fauna of their rights and ensured that Blake herself was born 'into subjagation'
