My parents aren't going to let me continue my nexuiz gaming unless I find a way to turn off all the gore.
Is there some way I could do this? or can someone send me an edited nexuiz that has it turned off?

Please help me

For a start:

cl_nogibs 1
cl_particles_blood 0
cl_particles_bloodshowers 0

If that isn't enough:

cl_particles_quality 0
or even
cl_particles 0

Honestly? Your parents need to stop sheltering you, and stop getting parenting advice from FOX News. Seeing splashes of incredibly unrealistic, pixelated chunks of beef fly through the air isn't going to make you a psychopath, or damage you in any way.

That aside, you can turn off gore in the menu. Go to Effects, and turn the 'Gibs' slider down to 'none'.

Wasnt there a little mod a while ago on the forum that turned gibs into confetti instead?
