If you have your mute on, you can't read what they're saying. I usually just click on another tab like 'notes' or 'info' so I can't view that chat, but I want to keep it on so I can say things like 'NH' or 'GG' for example.
Anyway, just ignore her. You have a right to say what you wish on the table (as long as its within rules and regulations), so if you have an opinion, don't be afraid to speak it. You should laugh about this, this woman is going out of her way to seek you out, sit at your table, and for what? Something as stupid as you having a different opinion about something. She is wasting her own time and thats it. Don't let it psych you out.
In fact, you could use this to your advantage, you know. This woman is obviously upset at you for your opinions on the matter. If she keeps bringing it up, stick to what you said. Don't be rude or anything. This will probably tilt her/make her more upset. If she is playing at the same table, its perfect for you because you can set her up to lose all her money to you. If you've upset a person, especially at a table, they're going to try and get revenge anyway they can. This could be through chat, following you around, and maybe trying to beat you with a bad hand/bluffing you. You most likely can get them to pay you off on your big hands because they want to do onto you what you did them (upset them). So, if anything, this is a blessing in disguise in my opinion. Keep you upset at you, keep your tilted, and take her money.
