In a conversation about water contamination in Flint, Michigan in an online forum, two individuals are making claims you are sceptical of and refuse to provide evidence to support their claims. 

They refuse to review the evidence you have presented to support your opinion. 

Despite the irritating nature of this exchange, you firmly adhere to your logical scientific argument without falling for the appeals to emotions or "trolling". 

What critical thinking habit of mind did you display?
