I'm assuming that your problem is with the phrase "load of crap," otherwise the implication of your conclusion is that everyone's intent for posting is to be hostile, otherwise they simply wouldn't post anything.
I used the phrase "load of crap" as an intentional rhetorical device in counterpoint to his assertion that science (and somehow evolution) has to remain silent on theological matters - the implication of his statement being that, on some level, science and theology are in opposition, that someone who opposes theology must be doing it on purely a scientific basis, and that since science "must remain silent," nobody can oppose theology.
So, the phrase "load of crap" served double duty - first, as an unveiled description, not of theology, but of his failed argument to silence opposition to theology - and, secondly, as an intentionally unscientific phrase highlighting that, even if it were the case that science had to remain silent about theology, it certainly isn't the only opposition to theology anyway.
There's actually a bit more to it than that, but that should give you at least some of the purpose behind my language, and why my intent, nor feelings, were hostile.
