so far, this is what I have, but I'm not sure if using the right thing where $nick is though:

on *:text:*:#christian-chat:{
if (*showing*me*the*hatred*and fascism* iswm $strip($1-)) {
msg x devoice # $nick
}

Im guessing you trying to do this, but i think your way would work to.

on *:text:*:#christian-chat:{
if (*showing*me*the*hatred*and fascism* iswm $strip($1-)) {
/mode $chan -v $nick
}

it might not be working as expected because the event was not closed, you didnt close yours either

Well your script works if you have a bot named X and a command on it that you message him to devoice nicknamehere there your script has no flaw except

has Dave said close your event.

Rule #1 if your gonna open a bracket (CLOSE IT) its like locking your front door of the house and leaving your backdoor unlocked, other things can come in "conflict"

theres a neat button in your Script Editor in mirc in the top right corner looks like {} if you press it and says bracket mismatch it means you didnt close your bracket "EVENT" properly.

your code should be more like this...
