Is there any grammar issue?
whatever they have to say about her, but they were very, very upset that this was even a thing and, to be honest, i was really surprised to see the reaction that i was seeing which was a lot of people upset about it. they were worried about being censored, and they looked at it as a bad thing, and i don't see how this is a bad thing at all. i don't know how you guys feel about it.
for my end of things, regardless of how someone might feel about her, or think about her, find me somebody on twitter over the past two years that's had more experience dealing with that sort of thing. you are talking about someone who's dealt with that sort of thing before. i'm not a fan of her, i'm neither dislike her, i respect her right to have her opinion, i like to respect anyone's right to have their opinion, as long as they don't attack people personally. a lot of the flak she gets back toward her goes personal, rather then, people don't really

You could say that this passage has grammar issues. For instance, in the first sentence "whatever they have to say about her, but they were very, very upset (...)", you could say that there is no reference for the personal pronoun they and the focus is changed because later on the personal pronoun "I" is used (" I was really surprised to see (...)").  So, is the speaker talking about them (whoever them refers to) or about himself? The fact is that this piece of text looks like an internal monologue.

Generally, in internal monologues, the ideas are presented as they pop up in the speaker's mind. They are not reordered for them to fit into the academically accepted style, that is, for them to be grammatically correct.  In a way, the reader finds himself lost in the speaker's train of thought. This style is similar to the oral style. An example of this is J.D. Salinger's The Catcher in the Rye.
