Then I'm still disagreeing. It is not a paradox. It can be logically resolved without any problem, although it requires clear thinking about how falsehood and negation works.
Let's go through this point by point.
1. A paradox is a statement that cannot be logically consistent. Any statement that has a logically consistent interpretation is therefore not a paradox.
Do you agree? We're going nowhere if we can't agree on the definition of a paradox.
2. Let us define what the possible false versions of your statement "everything I say is a lie" could be.
We can negate "lie", giving "everything I say is not a lie" or "everything I say is true".
Or we can negate "everything", giving "not everything I say is a lie" or "some things I say are true".
Both are completely reasonable and grammatically correct interpretations of the negation of that sentence.
If the only negation possible was "everything I say is true", then your statement would be a paradox. But it's not.
"Everything I say is a lie" can be false, meaning "some things I say are true". That particular statement is false, which does not contradict the statement "some things I say are true". There is a logically consistent interpretation of the sentence (albeit a non-obvious one), and so it is not a paradox.
What I meant in the previous post is this thread would be more sites to being a riddle game which has for more possibility to entertain rather than a thread full of paradoxes which will just serve to be a place for just that.
This thread seems to be working OK, as there are people who don't understand what is a paradox and what isn't.
