No, she's not, you're just framing it that way. She's given you the proof, that is, the content of that thread. You are now saying, 'well, what part of that thread?' And she's responded by telling you to go and read the source instead of asking which pieces of the source you should read. I would't agree that it's a majority of SV's users, but it is not an insignificant portion, and you can interpret what she's said ('large segment of sv') as either meaning 'a significant number of people on SV' or, as you are, 'a majority of people on SV.' Your response is both based on your refusal to read a source and you not clarifying what you assume the other person to be saying.
