The ACLU has taken a consistent stance on flag burning.  For it apparently, if these articles below are an indicator (source-ACLU.org)

• ACLU Calls Flag Desecration Amendment Assault on Free Speech; Says Measure Fails Very Principles Flag Embodies
• Reasons to Oppose the Flag Desecration Amendment
• ACLU Warns Against Flag "Protection" Amendment to Constitution; Says Bill Threatens Freedoms Represented By Stars-and-Stripes

A quick search found articles dating back to 1998.

So I know they will be immediately ready to defend this guy:

A Tucson man was arrested Tuesday for his role in the burning of a Mexican flag as part of a counterprotest at a pro-immigration rally.

At about 4:30 p.m. Tuesday, Tucson police cited Roy Warden, 58, on suspicion of assault, criminal damage and reckless burning, and then released him, according to Sgt. Decio Hopffer.

Oh, I grant that the charges are all directed at public safety and property issues, but I have to wonder if the same charges would have been issued at an immigrant group burning the American Flag.

I would hope so, but in the light of the attitudes towards the protests lately, I have to wonder.  Kids get bus rides home after skipping school, illegal immigrants self identify in rallies and are not detained…etc.

But regardless, it just seems to me that had that immigrant rights group done the burning and been arrested, they would be more likely to get ACLU representation then Mr Warden and his group.

And of course, this all still continues to avoid the real issues.
