Who follows robert spencer?
Short answer:
A bunch of trump-loving right-wingers, christians and an unhealthy dose of hindutva gangs ... he loves them so much that he wrote his name in Hindi

The number of pro-trump hashtags in the bio's of his followers are off-the-charts. Here're some examples:
# maga: 7114
# trump: 3168
# trump2020: 2118

The number of followers who associated themselves with hindu nationalism is 11920, which is naturally unexplainable

This shouldn't come as a surprise: The 2nd most popular location of his followers is India. This explains the insane dose of hindu nationalists following him.

These are just the followers I was able to categorize based solely on their bio's. Imagine what the real numbers would be!

Don't be intimidated cuz he has a large following. They're mostly trump-loving, modi-loving, Islam-hating individuals who're feeding off of his hatred!

You can suggest other accounts I can analyze similarly. In the meantime, check:
