And I would not recommend stay in low latency feature of Twitch. You are there to show people something, not to live chat with them. Opt-out of it and comeback to normal 30 seconds delay. Reasons to do this includes, but not limited to:

-1 -if gaming on a FPS, enemies might use your Twitch stream to find you. 30 seconds delay allows you to actually use counter-measures and employ disinformation tactics on your stream

-2 -if showing something, chat should be secondary, not primary. You're not on a live AMA, for that use Youtube LIVE (or chaturbate if that's your thing, I don't judge)

-3 -as said above, to give you time to react to your own mistakes

-4 -post processing for additional effects/reasons. Making a loop allows you to cut into mid-stream in some cases. This is an advanced use though, I only know of one twitcher that uses this

"You are there to show people something, not to live chat with them"

Many, many streamers expressly DO want to live chat with viewers. As a viewer, I don't like streamers that don't interact with chat. I may as well as watch a youtube video at that point. As a streamer, the entire point for me is to interact with people. If all I wanted to do was showcase something, I'd make youtube videos...

There are other methods one can use to avoid i.e. stream sniping besides having a long latency.

"You're not on a live AMA"

Twitch literally has a "Just Chatting" category. That said, there's nothing wrong with a streamer taking a break from the game to just chat for a bit. If you don't like that, instead of telling people how they should act, why not find a different streamer or use a different platform?
