Since you seem so keen to throw these words around, you must know well what they mean. So... what is the meaning of "blasphemy"? What is the meaning of "heretical"? Why would you bother adding "it seems" to "unforgiveable"... are you unsure of your position (which of course is unbiblical, as only one sin is described therein as unforgiveable, or didn't you know that?).
Your out-of-context comments don't help your case. If you are referring to a specific statement, quote it so that we can understand you.
Another thought... since, according to you, there is so much "utter and total blasphemy" on this forum, why are you here? Surely you are sinning by associating with such heinous unregenerate sinners such as us?
