They were out in Soho which is famous for being an LGBT hub harassing people for "sexual deviancy" telling people they were going to hell and needed to be "saved"

That doesn't sound like violent intimidation tactics. It might cause offence, yes, but a mixed group of unarmed men and women of different ages from various races chanting "Jesus Saves" in a street is hardly terrorism- it sounds more like a peaceful protest if anything (albeit, extremely unorthodox and counter productive. But again, this is within the character of charismatic movements). That doesn't change even if you think they're nutjobs/disagree with them. In fact, it's quite a refreshing change from that march in London a number of weeks ago. Street preachers aren't anything new in the UK. People probably wouldn't have even noticed if Turning Point hadn't used a video of them for content, and the Canary just wanted something to fearmonger over.

Soho is also famous for being a nightclub hub in general. I don't know the area though so I cannot tell if they're particularly targeting a gay bar or not.

However, seeing people call for violence or calling people terrorist over speculation is deeply disturbing.
