You are making a claim.
But I am not saying that the claim is true.
For the sake of argument you are though. I think you'd benefit from looking up the answer for "What is a claim in debate terminology?"
It could be possible that you don't believe what you are saying. But you present yourself like you do believe it.
No. The claim "truth doesnt exist" maintains that nothing is true. Thus, none of my claims need to be proved because I never said they are true.
Okay, now I am starting to understand where you are coming from. You seemed to have found a loophole exploit in standards of language, debate, and truth.
However, I believe I have found a fallacy in your exploit:
In a debate, two people have their own claim.
If nothing is true, then you say you do not have to defend your claim because you don't think the claim is true in the first place ("I dont need to prove my claim, since I never claimed that my claim is correct." "No. The claim "truth doesnt exist" maintains that nothing is true. Thus, none of my claims need to be proved because I never said they are true.").
If you accuse me of strawmanning over this, ima gonna lose it!
But, this is contradictory to the function of a debate. Two people are representatives for their chosen side on the topic. You can't represent the side that"nothing is true" because fighting for that is contradictory to what it means.
Every time you try to defend that nothing is true, you are contradicting the fundamentals of argumentation which is the highest and intelligent form of conversation.
In the words of a famous writer:
"If someone proved to me that Jesus isnt the truth, then I should prefer to remain with Jesus rather than with the truth."
Hypothetical that isn't reality.
I dont even know why you argued so far. Arguing against Christians is pointless
